5-(2-fluorophenyl)-1H-pyrrole-3-carbonitrile

The chemical structure of 5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile needs to be investigated in detail. This compound is composed of three parts.
The first is a pyrrole ring, which is a genus of a five-membered nitrogen-containing heterocycle. It has a unique electron cloud distribution. The lone pair of nitrogen atoms participates in the conjugated system, so that the pyrrole ring is electron-rich and exhibits unique activity in chemical reactions.
is subjoined to 2-fluorophenyl, and the fluorine atom is attached to the ortho-position of the benzene ring. The benzene ring has a conjugated large π bond and is a planar hexagonal structure with stable properties. Fluorine atoms can affect the electron cloud density of the benzene ring by inducing and conjugating effects, and then affect the reactivity of the groups connected to it. And the introduction of fluorine atoms has a significant impact on the physical and chemical properties of compounds, such as fat solubility and stability.
The tail is a formonitrile group, that is, a -CN group. The carbon and nitrogen in this group are connected by three bonds, which has a high polarity. The electron cloud is biased towards the nitrogen atom, making the formonitrile group electron-absorbing. This property not only affects the molecular dipole moment, but also plays an important role in the chemical activity of compounds. The formonitrile group can participate in many organic reactions, such as hydrolysis and addition.

There are several common methods for the synthesis of 5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile:
One is to use 2-fluorobenzaldehyde and malonitrile as the starting material, and first through the Knoevenagel condensation reaction to obtain the corresponding acrylonitrile intermediate. This reaction often needs to be carried out in the presence of an appropriate catalyst, such as an organic base such as piperidine or pyridine, and the solvent such as ethanol or methanol is heated and refluxed to make the reaction occur smoothly. The target product 5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile can be obtained from the obtained alkenonitrile intermediates through intramolecular cyclization. The cyclization step may need to be catalyzed by Lewis acids such as ZnCl ² or FeCl
Second, with 2-fluoroaniline as the starting material, it is converted into diazonium salt by diazotization reaction. The diazonitrile salt undergoes free radical addition reaction with acrylonitrile to form a fluorine-containing nitrile group substituted intermediate. Subsequently, under basic conditions, the intermediate undergoes intramolecular cyclization to construct a pyrrole ring, thereby obtaining the target compound. The diazotization reaction is usually carried out at low temperature with sodium nitrite and hydrochloric acid or sulfuric acid. The addition reaction of free radicals requires the introduction of appropriate free radical initiators, and the cyclization step requires the control of the type and dosage of bases, the reaction temperature and time.
Another synthetic path using halogenated aromatics and pyrrole derivatives as raw materials. 2-Fluorohalobenzene and 3-cyanopyrrole can be synthesized by C-C coupling reaction in the presence of transition metal catalysts such as palladium catalysts (such as Pd (PPh)) and ligands. 5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile can be synthesized. This reaction often requires appropriate bases such as potassium carbonate or sodium carbonate, toluene, dioxane, etc. as solvents to promote the reaction under heating conditions.
Each synthesis method has its own advantages and disadvantages. In practical application, it is necessary to consider the availability of raw materials, the difficulty of controlling reaction conditions, yield and purity requirements and other factors to choose the most suitable synthesis path.
