Nitration of 3-methyl-6,7-dihydro-1H-indeno[6,7,1-def]cinnoline and its N-substituted derivatives
摘要:
The nitration of 3-methylaceperidazine (3-methyl-6,7-dihydro-1H-indeno[6,7,1-def]cinnoline) and its N-substituted derivatives with nitric acid of different concentrations requires harsh conditions and is accompanied by dehydrogenation and dimerization of the initial compound.
Protonation, deuteration, and formylation of aceperidazylenes
摘要:
1H-1,2-Diazaphenalene derivatives in which the pyridazine ring is ortho- and peri-fused to acenaphthene and acenaphthylene (1H-indeno[6,7,1-def]cinnolines) have been synthesized. It has been found that electrophilic attack on these compounds is directed at C-6.
