Synthesis of metal-tetraazadiene complexes via ligand transfer; two routes to nickel- or platinum-tetraazadiene complexes [M(Ar2N4)(L)2]

Abstract

A novel route for the synthesis of metal-tetraazadiene complexes is reported involving the direct transfer of a Ar{2}N{4} ligand from [Ni(Ar{2}N{4}){2}] to Ni}0{ and Pt}0{ centres in the presence of t-butylisocyanide, resulting in [M(Ar{2}N{4})(t-BuNC){2}] species. For M @? Pt the latter complexes can also be prepared by reaction of the zerovalent isocyanide complex with the appropriate azide or by addition of t-BuNC to [Pt(Ar{2}N{4})(COD)].
