The influence of electron-accepting substituents in pyridines on the regioselectivity and the rate of the nucleophilic wedge reaction in the CH bonds of pyridines was determined. The possibility of synthetic use of this reaction to obtain the corresponding aldehydes was evaluated. The influence of temperature, the possibility of using catalysts, the method of control and analysis of the reaction are proposed. The reaction of silylformamidine with electron-enriched heterocycles on the example of thiophene was studied and the influence of electron-accepting substituents on the course of the reaction was determined. The most favorable conditions for the reaction, substituents that activate the reaction and the possible synthetic use of silylformamidine were determined.
