Reactions of 1-Trichloromethyl-substituted Amines with Potassium tert-Butoxide

Takamatsu, Masanori,Sekiya, Minoru

, p. 3098 - 3105 (2007/10/02)

The reaction of 1-trichloromethyl-substituted amines with tert-butoxide has been shown to provide important entries into a number of groups of functionalized amines, i.e., 2,2-dichlorovinylamines (which are also convertible into chloroynamines with a large excess of tert-butoxide), 2,2-dichloroenamines, N-(α-dichloromethylbenzylidene)amines and 2,2-dichloroaziridines.The formation of the products in individual cases depends upon the structure of the amine substrate.Keywords - 1-trichloromethyl-substituted amines; potassium tert-butoxide; 2-chloroynamines; 2,2-dichloroenamines; N-(α-dichloromethylbenzylidene)amines; 2,2-dichloroaziridines; elimination of hydrogen chloride
