Gold(I) complexes bearing monophosphole ligands were synthesized, and their electronic and steric properties were compared to those of their triphenylphosphine-based counterparts. Cationic phosphole-based gold(I) complexes are active and selective in enyne cycloisomerization and in olefin cyclopropanation, with a good correlation between the ligand σ-donor ability and the catalytic activity. For the
合成了带有单磷原子配体的金(I)配合物,并将其电子和位阻特性与基于三苯基膦的对应物进行了比较。阳离子磷基金(I)络合物在烯炔环异构化和烯烃环丙烷化中具有活性和选择性,在配体σ供体能力和催化活性之间具有良好的相关性。对于最有效的配体,请分离出1-苯基-2,3,4,5-四甲基磷脂(TMP),该化合物是高活性,选择性和稳定的阳离子[Au(TMP)(CH 3 CN)] SbF 6络合物。
