Abstract

Abstract The trichloromethyl group served as a useful leaving group in nucleophilic displacement reactions by a variety of substituted amines and alcohols (the latter under base catalysis) on 2-trichloromethyl-5-methyl-1, 3, 4, 6, 9b-pentaazaphenalene (1a) and 2- trichloromethyl-4-cyano-1, 3, 6, 9b-tetraazaphenalene (2a). The reaction conditions were mild and the yields of the corresponding 2-substituted amino and alkoxy derivatives were ...
