The preparation of 7,9-dibromo-2-tribromomethyl-5-trichloromethyl-1,3,4,6,9b-pentaazaphenalene (1c) and 7,9-dibromo-2,5-bis(tribromomethyl)-1,3,4,6,9b-pentaazaphenalene (1d) is described.Reaction of 1c with various nucleophiles cenverted it to the corresponding 7,9-dibromo-2,5-bis-substituted derivatives, the trihalomethyl groups serving as leaving groups.Displacement, first of one tribromomethyl group on 1d by pyrrolidine, and then by various nucleophiles on the remaining tribromomethyl group led to several mixed 2,5-disubstituted derivatives.
