An unprecedented palladium(II)-catalyzed biomimetic aliphatic acyl (-COR) group transfer was observed from acyl-α-peroxycoumarins to the ortho C?H sites of directing arenes. Here, the C?H activation is associated with a concomitant acyl group transfer via a Pd(II)-catalyzed, redox-neutral process. While methods for ortho aroylation (-COAr) are well documented ortho acylation (-COR) processes are scarce, hence the present redox-neutral method is most ideal for o-acylation of directing substrates.

Rh(III)-catalyzed acetylation of sp2 C?H bonds has been realized using paraformaldehyde as an acetylating reagent. This procedure features simultaneous formation of two C?C bonds, external oxidants free, and water as the sole byproducts, thus offering an environmentally benign acetylation of arenes. A range of functional groups tolerance were observed.

An efficient carbo-acylation reaction of 2-arylpyridines with α-diketones via Pd-catalyzed C-H bond activation and C-C bond cleavage in the presence of TBHP was developed that generated aryl ketones in good yields. The highly selective formation of aryl ketones was observed when 2-arylpyridines reacted with aromatic/aliphatic α-diketones.
