• Vilsmeier
• dimethylaminonaphthalenes
• benzonaphthodiazocines

The novel fused heterocyclic systems 7,8,13,14-tetrahydrobenzo[b]naphtho[1,2-f][1,5]diazocine and 7,8,13,14-tetrahydrobenzo[b]naphtho[2,1-f][1,5]diazocine were prepared in moderate yields in a one step reaction by Vilsmeier formylation of 1-dimethyl-aminonaphthalene or 2-dimethylaminonaphthale ne, respectively, by way of the ';t-amino effect';. Novel rearranged by-products were formed from 2-dimethylaminonaphthalene.
