Abstract
6,7-Dihydro-4-methyl-1H, 4H-benzo[e, f]-s-indaceno[2, 3-d]pyrazole (IV a), 1-carbaimido-6, 7-dihydro-4-methyl-1-H, 4H-benzo[e, A-s-indaceno[2 , 3-d]pyrazole (IVb) and 6, 7-dihydro-4-methyl-1H, 4H-1-thiacarbamidob enzo [e, f]-s indaceno-[2, 3-d]pyrazole (IVc) have been synthesised by reacting 8-formyl-7-methyl-4, 5, 7, 8-tetrahydro-9H-benzo[e, f]-s-ind acen-9-one (III) with hydrazine hydrate, semicarbazide hydrochloride a nd thio-semicarbazide hydrochloride, respectively. These compounds hav e been characterised through their PMR and (CMR)-C-13 spectral analyse s.
