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 reaction of 1a with N-chlorosuccinimide proved not to be a useful route to 1e but instead led primarily to substitution of position 7 and/or 9 by chlorine.
