摘要:
A robust palladium catalyst system supported by the hybrid ligand N-heterocyclic carbene along with a phosphine derived from ferrocene has been discovered for the Suzuki cross-coupling reaction. This novel system effectively catalyzes the cross-coupling of aryl bromides and phenylboronic acid with up to 20,000 TONs and 10,000 h(-1) TOFs to produce biaryl products in excellent yields.
