A novel and efficient Pd-catalyzed C–H acetoxylation is described. The approach uses R2(O)P as a directing group to synthesize various substituted 2′-phosphoryl biphenyl-2-OAc compounds.

we report an approach for direct diarylations of 2-bromobiphenyls or bromobenzenes. As a result, a wide range of triphenylenes with various substituents have been synthesized in good yields. These triphenylenes are expected to be employed in the “bottom-up” synthesis of functional aromatic molecules in material science.

A novel R-2(O)P-directed Pd(II)-catalyzed C-H hydroxylation to synthesize various substituted 2'-phosphorylbiphenyl-2-ol compounds is described. Notably, the reaction operates under mild conditions and shows good functional group tolerance, high selectivity, and yield.
