用P(OR)3在σ-π-乙酰基配合物Fe2(CO)6(CCPh)(PPh2)上亲核攻击合成了磷酸-甜菜碱(ylide-carbene)配合物,并对三乙基亚磷酸酯衍生物Fe2(CO)6{C[P(OEt)3]CPh}(PPh2)进行了单晶x射线研究,证实了一种新型的2碳3电子配体的存在。
Phosphonium–betaine (ylide–carbene) complexes have been synthesised via nucleophilic attack by P(OR)3 on a σ-π-acetylide complex Fe2(CO)6(CCPh)(PPh2), and a single crystal X-ray study of the triethylphosphite derivative Fe2(CO)6{C[P(OEt)3]CPh}(PPh2) has con-firmed the presence of a new type of 2-carbon, 3-electron ligand.
