Abstract:

The palladium-catalyzed direct arylation of several (hetero)arenes via direct C−H bond activation using aryl halides has brought significative advances on the synthetic area in recent years. Such couplings are very attractive to replace classical palladium catalyzed type couplings, once they do not require the preliminary synthesis of one or two organometallic derivatives. Therefore, these reactions are atom-economical and produce less waste. Up to now, to promote a cross-coupling reaction with the selenophene ring (1), a previous activation, either as a halide or as an organometallic (B, Mg, Sn and Zn) is required. This fact and our continuous interest in the synthesis of organoselenium compounds, prompted us to explore a new approach on the palladium-catalyzed direct arylation of selenophene (figure 1).
