Peracetic acid can be used universally as a source of acetate and an oxidant for the selective acetoxylation of C–H bonds in compounds containing ortho-directing groups, catalyzed by Pd(OAc)2. Compared to previous procedures, where persulfates and PhI(OAc)2 were used, the new protocol provides significant improvements in atom efficiency, product yield, substrate scope, cost, scalability, and environmental impact. |
