Metal-assisted CO labilization and intramolecular hydride transfer reactions in heterobimetallic µ-phosphido–hydrido carbonyl complexes
Abstract
The oxidative addition of the P–H bond of (OC)5M(PPh2H)(M = Cr, Mo, W) to zerovalent platinum complexes initially forms heterobimetallic µ-phosphido terminal hydrido complexes which readily rearrange via bridging carbonyl and platinum–terminal carbonyl intermediates to give the µ-phosphido-µ-hydrido complexes (OC)4M(µ-PPh2)(µ-H)Pt(PR3)2.
