Novel synthesis of a phosphinidene oxide-κP(RPO, R = ButCH2–) complex of rhenium(I) from a phosphaalkyne precursor. Crystal and molecular structure of [ReCl(Ph2PCH2CH2PPh2)2{P(O)CH2But}]

Abstract
The first example of the transformation of a phosphaalkyne to a phosphinidene oxide-κP ligand is reported.
