摘要

Abstract The preparation of 7, 9-dichloro-2, 5-bis (trichloromethyl)-1, 3, 4, 6, 9b- pentaazaphenalene (1e) by the chlorination of 2-trichloromethyl-5-methyl-1, 3, 4, 6, 9b- pentaazaphenalene (1a) using molecular chlorine is described. Displacement of one or both trichloromethyl groups of 1e by a variety of nucleophiles led to the corresponding 7, 9- dichloro-2, 5-bis-substituted or 7, 9-dichloro mixed 2, 5-disubstituted derivatives. The ...
