Novel insertion of [M(PR3)2] fragments (M = Pd, Pt) into the strained phosphorus–carbon bond of the phosphirene complex [W(CO)5(PhPC2Ph2)]. Crystal and molecular structure of [PtW(CO)5(PEt3)2(PhPC2Ph2)]

Abstract

The striain phosphirene ring in [W(CO)₅(PhPC₂Ph₂)] readily undergoes insertion of [M(PR₃)₂] fragments (M = Pd, Pt) to give complexes in which phosphorus bridges two different metal atoms.
