N,N-Dimethylamino-2-pyridine

N 2O CN, that is, the dicyanyl anion, whose central nitrogen atom is connected to two cyano groups (CN). From the perspective of chemical structure, the cyanyl group is connected by a triple bond between the carbon atom and the nitrogen atom, showing a high degree of unsaturation.
In the dicyanyl anion, the central nitrogen atom adopts the method of sp hybridization. This is because the central nitrogen atom needs to form a linear structure with the two cyano groups to reach the stable state with the lowest energy of the system. After sp hybridization, the central nitrogen atom has two sp hybridized orbitals, which stretch 180 ° in space and form a sigma bond with the carbon atoms in the two cyano groups, respectively.
At the same time, the two p-orbitals of the central nitrogen atom that did not participate in the hybridization are perpendicular to each other, and overlap with the p-orbitals of the carbon atoms in the two cyano groups, respectively, forming two delocalized large π bonds. This structure endows the dicyanoanion with unique electron cloud distribution and chemical activity.
This structure causes the dicyanoanion to exhibit specific properties in chemical reactions. For example, due to the existence of delocalized large π bonds, the electron cloud can be delocalized in the entire ion system, making the ion relatively stable, and at the same time making it have certain nucleophilicity. Under suitable conditions, it can participate in chemical reactions such as nucleophilic substitution. Due to its unique chemical structure and properties, it is of great significance and application in many chemical fields such as organic synthesis.

The main uses of diazo-dihydroxyborane are as follows:
First, it is of great significance in the field of weapon manufacturing. Because of its special chemical and physical properties, it can be used to create stronger and lighter weapon materials. For example, when building a sword, incorporating this substance can make the blade of the sword sharper and tougher, and it is not easy to roll and break, which greatly enhances the practicality and lethality of the weapon on the battlefield, and helps the soldiers gain an advantage in battle.
Second, it has a significant effect in alchemy and pharmaceuticals. It can be used as a special medicine guide or a key ingredient in the refining of medicinal pills. Ancient alchemists believed that the unique energy and chemical properties contained in this substance could stimulate the magical effects of medicinal pills through specific refining methods. Or it can improve the effect of medicinal pills to prolong life, or it can enhance the ability of medicinal pills to treat intractable diseases, and help to achieve the goal of immortality or cure serious diseases.
Third, in the production of feng shui magic tools, it is also indispensable. According to the theory of feng shui, the special aura and energy possessed by this substance can make magic tools with strong feng shui adjustment ability. For example, the pointer made into a feng shui compass can more accurately sense changes in the aura field and assist feng shui masters in investigating the feng shui pattern of yin and yang houses; or it can be made into an ornament to ward off evil spirits and placed in the house to dispel evil energy, protect the peace of the house, and create a good feng shui environment.

Nowadays, there are things called N% 2CN + -, which is the group of diamino groups. In the art of organic synthesis, this group has a number of excellent length.
First, this group is rich in reactivity. Due to its amino structure, nitrogen atoms have solitary pairs of electrons, which can be used as nucleophiles and react with many electrophiles. In case of halogenated hydrocarbons, they can be replaced by nucleophiles to form new carbon-nitrogen bonds. This is a key step in the construction of complex organic molecular structures. Just like a skilled craftsman, with precise skills, all the components are connected to form a grand building of organic molecules.
Second, the existence of N% 2CN + - can significantly adjust the polarity of molecules. The amino group is a strong polar group, which can increase the interaction between molecules and polar solvents and improve their solubility. This is extremely important in the operation of organic synthesis. Due to its good solubility, the reaction materials can be uniformly mixed, and the reaction can be carried out more easily. It is like driving on a smooth track, accelerating the reaction process and improving the yield.
Third, the group of this diamino group can form hydrogen bonds between molecules. Although the force of hydrogen bonds is weaker than covalent bonds, it has a great impact on the physical properties such as the aggregate structure, melting point, and boiling point of molecules. When synthesizing materials with specific physical properties, the characteristics of hydrogen bonds can be used to achieve the desired effect. For example, in the preparation of some functional polymer materials, the action of hydrogen bonds can make the molecular chains entangle and cross-link with each other, enhancing the mechanical properties of the material.
Furthermore, N% 2CN + - can be used as a guide group. In some reactions, it can guide the reaction to selectively occur at a specific location. This is like a compass that indicates the direction of the reaction, allowing synthetic chemists to precisely control the reaction check point and prepare organic compounds with specific structures and functions, which greatly enhances the efficiency and accuracy of synthesis.

What are the physical properties of N% 2C N - binary amino-2 - to it? The following is an answer to this question in the ancient classical Chinese style of "Tiangong Kaiwu".
Fu N% 2C N - binary amino-2 has various physical properties. Its shape is, under normal circumstances, or an invisible state, hidden among various things, as if there is nothing, but it exists; or it is in the shape of fine particles, as fine as smoke and dust, depending on the need for precision tools.
Its color is often plain and pure, mostly colorless and transparent, like clear water, without all kinds of colors; occasionally light color, like the faint mist of morning mist, elegant and difficult to observe.
In terms of its quality, it feels smooth or greasy to the touch, and it is like a flowing cloud passing through the hand without any blockage; or it is viscous, and it can be pulled into strands. Its specific gravity is more ordinary, or it is as light as a feather, which can float in the air and move with the wind; or it is as heavy as a stone, which sinks in water but does not float, and can be placed in various objects, which can be stable.
Its taste, smell it, or it is tasteless, like the breath of the void, does not attract the observation of the sense of smell; or it has a slightly pungent smell, which makes the nose uncomfortable; or it has a slightly sweet taste, but the taste is light and difficult to distinguish, and it needs to be tasted carefully.
Its solubility, in various solvents, or easily soluble in water, melts when entering water, just like snow melts in rivers, leaving no trace; or it is difficult to dissolve in water, floating on water, and distinct; in other solvents, such as alcohols, ethers, etc., also have different manifestations, or soluble or insoluble, depending on its nature.
Its volatility, or strong volatility, is fleeting when placed in an open device, like a breeze, and there is no trace; or its volatility is weak and left standing for a long time, and its amount is slightly reduced.
These are the general physical properties of N% 2C N -binary amino-2. However, the physical properties are complicated, and all kinds of empirical evidence and research are needed to be exhausted.

If you want to make a device with N% 2CN, there are two methods. First, you can use the technique of reconciling yin and yang. Find the place where the two qi of yin and yang converge between heaven and earth, and use the Qiankun stone as the base to attract the spiritual energy of heaven and earth into it. With the wonders of blending yin and yang qi, reconcile the nature of the stone, so that it has the power to absorb and release N% 2CN. When casting the spell, you need to have no distractions in your heart, guide the spiritual energy with spiritual thoughts, and arrange the Qiankun stones according to the position of gossip. When the yin and yang qi are integrated, this device will be completed. However, in this process, you must choose a good time to avoid the day of yin and evil, in order to prevent evil energy from entering and destroying its spiritual effect.
Second, you can borrow the principle of the five elements living together. First take the five elements of gold, wood, water, fire and earth, choose stainless steel from gold, choose thousand-year-old spiritual wood from wood, use water from spiritual springs for water, fire from the core of the earth, and earth to find the essence of yellow soil. Arrange the four things in the order of the five elements, gold generates water, aquatic wood, wood generates fire, fire generates earth, and native gold, and cycle. Place a jade plate in the center and inject the essence of N% 2CN into it. Then roast it with the true fire of samadhi, so that the power of the five elements and the essence of N% 2CN can penetrate each other. During this process, the heat is particularly critical. If the fire is large, the object will be destroyed, and if the fire is small, the strength will be insufficient. After the five elements and the essence of N% 2CN are integrated, the obtained tool can be used after cooling.
Both of these techniques require profound cultivation and exquisite skills. If there is a slight mistake, all previous efforts will be wasted. The person who makes the tool should be in awe and strictly abide by the ancient method in order to achieve this exquisite tool.
