Use of Formate Salts as a Hydride and a CO₂ Source in <i>PGeP</i>-Palladium Complex-Catalyzed Hydrocarboxylation of Allenes

Abstract

Use of formate salts as a hydride as well as a CO2 source was achieved in a PGeP-palladium complex-catalyzed hydrocarboxylation of allenes through a highly efficient decarboxylation-carboxylation process. This reaction proceeds under mild conditions and provides an alternative strategy for utilizing formate salts as a C1 source.
