Combining diaryl-calixarenyl phosphines with [Ni(cod)2] resulted in highly active KumadaâTamaoâCorriu cross-coupling catalysts. With one of the ligands, TOFs up to 439â000 mol(ArBr) mol(Ni)â1 hâ1 were observed in the reaction of 1-bromonaphthalene with PhMgBr. The systems were also found to be active at room temperature with aryl chlorides.
                                    将二芳基-萼萼烯基膦与[Ni(cod)2]结合,可得到高活性的 KumadaâTamaoâCorriu 交叉偶联催化剂。使用其中一种
