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.
已经发现由杂配体N-杂环卡宾与衍生自二茂铁的膦一起支撑的稳健的钯催化剂体系可用于Suzuki交叉偶联反应。该新颖的系统有效地催化芳基溴化物和苯基硼酸与高达20,000 TONs和10,000 h -1 TOF的交叉偶联,从而以优异的收率生产联芳基产品。
