Abstract
Treatment of diaryloxy- and triaryloxybenzenes in the presence of a Pd(TFA)2 catalyst and an AgOAc oxidant produces the corresponding benzobis- and benzotrisbenzofurans in good yields through double and triple intramolecular C–H/C–H coupling reactions, respectively. Treatment of diaryloxy- and triaryloxybenzenes in the presence of a Pd(TFA)2 catalyst and an AgOAc oxidant gives rise to the corresponding benzobis- and benzotrisbenzofurans in good yields through double and triple intramolecular C–H/C–H coupling reactions, respectively.Keywords
