Abstract

The carbonylation of phenyl bromide catalyzed by Co (OAc) 2 has been investigated with PhCOPh as a sensitizer under visible light in the presence of basic additive. With strong base CH3ONa, PhCOOCH3 is produced in 70% yield with 100% selectivity, the similar results are also obtained with a stronger base (CH3) 3CONa. However, with another strong base NaOH, the yield of the ester is only 40%. On the other hand, with weak base NaOAc ...
