The chemical properties of (trimethylmethyl) to its (trimethylbenzyl amine) are generally special. This compound, whose molecules contain the combination of specific atoms, results in the chemical specialization.
First, it has a certain degree of chemical properties. The chemical properties of different atoms are different, and the chemical properties of benzyl methyl groups in trimethylbenzyl amines make the chemical molecules uneven and generate chemical properties. This property makes it soluble in the chemical solution, and the chemical molecules can attract each other by the chemical action.
Furthermore, it has the activity of nuclear or chemical. The benzene in the benzyl part has the characteristics of rich molecules, and can be used for nuclear substitution and other reactions. For example, it can be attacked to make benzene be substituted. The methyl part is stable in phase, but under certain conditions, such as oxidation or high temperature, it may also generate reaction, and its alpha-reaction can be activated. It is also worth noting that
and its acidic properties are also worth noting. There are solitary ions on the nitrogen atom of trimethylbenzylamine, which can accept ions and show weak properties. In an acidic environment, it can be combined to form atoms. This property makes it specific in the acid reaction system, and can be used in separation, extraction, and other operations.
And because its molecules contain aromatic alkyl groups, it has certain qualitative properties. The combination of aromatics and aromatics makes the molecule able to resist the attack of partial normalization, and the alkyl group and alkyl group also provide a certain degree of stability. However, in the case of strong components such as oxidation and acid, it will still cause biochemical reactions, resulting in molecular modification.
Therefore, the chemistry of (trimethyl) to its (trimethylbenzylamine), determined by its molecules, is of great significance in the fields of synthesis and chemical analysis under different chemical environments.

Triethylamine is an organic compound. It is a colorless to light yellow transparent liquid, has ammonia odor, is alkaline, and can be miscible with water, alcohols and ethers. Its physical properties are many, as detailed below:

To prepare 4- (triethylmethyl) pentyl-3-enonitrile, you can do it according to the following method.
First take the appropriate halogenated hydrocarbons, such as the halogenated compounds containing the triethylmethyl structure, and the carbon connected to the halogen atom needs to have the appropriate activity for the subsequent reaction. In addition, nucleophiles containing cyanide groups are commonly used, such as sodium cyanide (NaCN) or potassium cyanide (KCN).
In a suitable solvent, such as dimethyl sulfoxide (DMSO) or N, N-dimethylformamide (DMF), such solvents have good solubility and promotion of nucleophilic substitution reactions. Mix the halogenated hydrocarbons with nucleophilic reagents to control the reaction temperature. Generally speaking, moderate heating, between about 50 and 80 degrees Celsius, can accelerate the reaction process. The cyanoanion (CN) in the nucleophilic reagent, because of its strong nucleophilicity, will attack the carbon attached to the halogen atom in the halogenated hydrocarbon, the halogen atom leaves, and a nucleophilic substitution reaction occurs, resulting in the target product 4- (triethylmethyl) pentyl-3-enonitrile.
In addition, alkenyl halide can also be used with triethylmethyl-containing metal-organic reagents, such as Grignard reagent or lithium reagent, to first metallize to form a carbon-metal bond. Afterwards, it reacts with a cyanide source, such as cuprous cyanide (CuCN). This reaction is carried out at low temperature to room temperature in an anhydrous and oxygen-free inert gas protective atmosphere. The metal-organic reagent reacts with the alkenyl halide for metal exchange or nucleophilic addition, and then interacts with the cyanide source to generate 4- (triethyl) pentyl-3-enonitrile. During operation, it must be noted that the metal-organic reagent is extremely sensitive to water and air, and the reaction system must be kept dry and oxygen-free.
In addition, the nucleophilic substitution reaction of the nucleophilic substitution reaction can be designed to construct the target molecular skeleton with compounds containing ethylene bonds and suitable leaving groups and nucleophilic reagents substituted with triethylmethyl groups, and then the cyano group is introduced by appropriate means. For example, the nucleophilic reagent is used to replace the leaving group to form the intermediate product, and then the intermediate product is reacted with a suitable cyanide reagent to achieve the introduction of the cyanide group, and finally synthesize 4- (triethyl) pentyl-3-enonitrile. The whole process requires fine regulation of the reaction conditions, including the amount of reagent, reaction temperature, reaction time, etc., to ensure high yield and purity.
