Abstract

Cross-coupling of benzylic carbonates with heteroarylboronic acids successfully proceeded in the presence of the palladium catalyst that was generated in situ from [Pd(η3-C3H5)Cl]2 and a chelate bisphosphine DPPPent. Various heteroarylboronic acids were applicable to the catalytic cross-coupling, giving the desired benzylated heteroaromatics in high yields.
