SUZUKI-MIYAURA COUPLING OF BENZYLIC CARBONATES WITH HETEROARYLBORONIC ACIDS

摘要

Cross-coupling of benzylic carbonates with heteroarylboronic acids successfully proceeded in the presence of the palladium catalyst that was generated in situ from [Pd(eta3-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.
