An efficient synthesis of novel aryl/heteroaryl‐substituted thieno‐fused heterocycles, that is, thieno[2,3‐ b ]thiophenes, thieno[2,3‐ b ]indoles, and pyrazolo[3,2‐ c ]thiophenes, involving radical‐mediated cyclization of 2‐(2‐bromoheteroaryl)‐3‐methylthio‐3‐aryl/heteroaryl acrylonitriles has been reported.
