A visible-light-driven carboxylation of aryl and alkenyl triflates with CO2 is developed by using a combination of Pd and photoredox catalysts. This reaction proceeds under mild conditions and can be applied to a wide range of substrates including acyclic alkenyl triflates.

A palladium-catalyzed β-C(sp3)–H arylation of aliphatic ketones by using acetohydrazide as a transient directing group has been developed. The reaction proceeds through a less-favored [5,5]-bicyclic palladacycle intermediate and is promoted by a pyridine ligand.
