摘要：

A novel efficient synthesis of 2‐N‐(benzo[b]thiophen‐2‐yl)benzo and heterofused‐1,2,3‐triazoles was achieved by the diazotisation of 2‐amino‐4,5,6,7‐tetrahydrobenzo[b]thiophene‐3‐carbonitrile and ethyl‐2‐amino‐4,5,6,7‐tetrahydrobenzo[b]thiophene‐3‐carboxylate and coupling with selected aromatic and heterocyclic amines followed by air oxidation in the presence of cupric acetate.
