Binary role of an ylide in formation of a terminal methylidene complex of niobium†
Abstract
The first structurally characterized niobium(V) complex possessing a terminal methylidene ligand is reported in high yield from the reaction of [(Ar′O)2Nb(CH3)2Cl] (Ar′ = (2,6-CHPh2)2-4-tBu-C6H2) and two equivalents of H2CPPh3.
