(α-Triphenylphosphonio)methylidene imido complexes of molybdenum, tungsten and rhenium: the first complexes exhibiting metal–ligand multiple-bonding with two carbon as well as two nitrogen centres
摘要:
报告了具有四个Ï-供体配体的四面体配合物[Mo(NBut)2(CHPPh3)2]、[W(NBut)2(CHPPh3)2]和[Re(NBut)3(CHPPh3)]的合成;W(NBut)2(CHPPh3)2]的 X 射线结构显示,亚氨基配体[NBut]和(δ-三苯基膦)亚甲基官能团[CHPPh3+]都与 d0 金属中心发生了强烈的Ï-相互作用。
