The synthesis method of pyrrole-2-formonitrile has been known in ancient times, and it is described by you today.
One method is to use pyrrole-2-formic acid as the starting material. First, pyrrole-2-formic acid is heated with thionyl chloride, and the two are combined. The carboxyl group of pyrrole-2-formic acid reacts with thionyl chloride to produce pyrrole-2-formyl chloride. This process needs to be controlled by temperature, and it should not be controlled if it is too high or too low. If it is too high, side reactions will occur, and if it is too low, the reaction will be delayed. Next, the obtained pyrrole-2-formyl chloride is reacted with sodium cyanide in a suitable organic solvent, such as dichloromethane. The two phases interact, and the chlorine atom of formyl chloride is replaced by a cyanyl group, so pyrrole-2-formonitrile is obtained.
The second method can be started from pyrrole. First, pyrrole is reacted with acrylonitrile in the presence of a suitable catalyst, which may be a metal salt such as zinc chloride. The activity check point of pyrrole is added to acrylonitrile, and then a series of reactions such as cyclization and rearrangement can also obtain pyrrole-2-formonitrile. In this process, the amount of catalyst, reaction time and temperature are all key factors, and must be precisely controlled in order to make the reaction smooth and obtain a higher yield.
The third method uses halogenated pyrrole as raw material. For example, brominated pyrrole and cuprous cyanide are heated in an organic solvent under specific reaction conditions. The halogen atom reacts with the cyanide group in the cuprous cyanide to obtain pyrrole-2-formonitrile. This reaction requires careful regulation of the pH of the reaction system, reaction temperature and other conditions to ensure the efficient progress of the reaction.
All kinds of synthesis methods have their own advantages and disadvantages. In practical application, when considering various factors such as the availability of raw materials, the difficulty of reaction conditions, and the high or low yield, choose the most suitable one and use it.
