Reaction of isocyanides with a molybdenum complex containing a tridentate silyl-phosphineligand: the Si ligand effect on site preference of the isocyanide ligands

Abstract

A molybdenum trihydride complex containing a tridentate silyl-phosphine ligand reacts with isocyanides to give isocyanide complexes, in which the Si atom and the isocyanides are cis to each other; the preferred configuration in the resulting complexes is reasonably explicable provided the Si fragment is acting as a good π-acid ligand.
