Boryl-Assisted Hydrogenolysis of a Nickel-Methyl bond


Natalia Curado, Celia Maya, Joaquin Lopez-Serrano and Amor Rodriguez Chemical Communications 2014, Vol. 0, DOI: 10.1039/C4CC07616H

A stable Nickel(II) methyl complex containing a diphosphinoboryl (PBP) pincer ligand is described. Mechanistic studies on the hydrogenolysis of the Ni-Me bond suggest a metal ligand cooperation mechanism that involves the intermediacy of a σ-B‒H Ni(0) species that further undergoes B‒H oxidative addition to form a Ni(II) hydride complex.
