Differing modes of co-ordination are reported for complexes of platinum(0) containing the phospha-alkene P(mesityl)CPh2, e.g. in Pt(triphos)P(mesityl)CPh2}, [triphos =(PPh2CH2)3CMe], the phospha-alkene is η2-bonded to the metal whereas in PtP(mesityl)CPh2}3 and PtP(mesityl)CPh2}2(PCBut) it is η1-co-ordinated and the last two complexes are the first isolated compounds containing only phospha-alkene or phospha-alkyne ligands.
据报道,含有磷烯烃 P(mesityl)CPh2 的铂 (0) 配合物有不同的配位模式,例如在 Pt(triphos)P(mesityl)CPh2}、[triphos =(PPh2CH2)3CMe] 中,磷烯烃与金属以 η2-键合,而在 PtP(mesityl)CPh2}3 和 PtP (mesityl)CPh2}2(PCBut) 它是α1-配位的,最后两个配合物是第一个分离的仅含有磷-烯烃或磷-炔配体的化合物。
