A Convenient Procedure for the Preparation of Bis(dialkylamino)malononitriles

Abstract

N,N,N′,N′-Tetraalkylchloroformamidinium chlorides react with trimethylsilyl cyanide without solvent to give bis(dialkyl­amino)malononitriles, which can be distilled off from the reaction mixture in vacuo.

Key words

iminium salts - N,N,N′,N′-tetraalkylchloroformamidinium chlorides - trimethylsilyl cyanide - bis(dialkylamino)malononitriles
