Abstract:

The benzo[b]thiophene functionalization with benzyl groups at C-3 has been a synthetic challenge. Indeed, up to the date, few efforts have been successful in the achievement of this goal, and all of them involving drastic experimental conditions. In this opportunity, trying to synthesize new benzo[b]thiophene frameworks, we inform the nonexpectable obtaining of benzo[b]thiophene dimers linked by a C-3 bond. In this sense, we think that this interesting experimental finding could lead to develop a new method to synthesize 3- substituid benzo[b]thiophene with different kinds of benzyl alcohols.
