Carboxylative coupling reaction of five-membered (chloromethyl)heteroarenes with allyltributylstannane catalyzed by palladium nanoparticles

Palladium-catalyzed chemical fixation of CO2 is successfully achieved using the π-allyl group related to heterocycles as a carbon-based ligand. The PdNPs generated in situ played a key role for the success in the carboxylative Stille coupling reaction.54
