Abstract

The first electrochemical dehydrogenative C-S bond formation leading to thienoacene derivatives is described. Several thienoacene derivatives were synthesized via dehydrogenative C-H/S-H coupling. The addition of nBu4 NBr, which catalytically promoted the reaction as a halogen mediator, was essential.
