The novel 1-substituted 4,5,7,8-tetrahydro-3H-6,8 b-dithia(8a-S lV) -1,2a,5a-triaza-8a-azoniadicyclo[a,cd]indene-2(1H)-thione bromides, the corresponding 8b-selena(8b-SeIV) derivatives, and 1-substituted 4,5,8,9-tetrahydro-3H,7H-6,9b-dithia(9b-S IV) -1,2a, 5a-triaza-9a-azoniacyclopenta[jk]fluorene-2(1H)-thione bromide and the corresponding 9b-selena(9b-Se IV) derivatives were synthesized by the reaction of tetraazapentalene derivatives 1a, b and 2a, b with 2-bromoethyl and 3-bromopropyl isothiocyanates, respectively, in good yields.
