Probing stepwise reaction of NNP-ligand copper(I) complex with elemental sulfur by using N-heterocyclic carbene as a trapper.

Abstract

The dinuclear NNP-ligand copper(I) complex [o-N═CH(C(4)H(3)N)-PPh(2)C(6)H(4)](2)Cu(2) (1) has been synthesized by the reaction of (CuMes)(4) (Mes = 2,4,6-Me(3)C(6)H(2)) with N-((1H-pyrrol-2-yl)-methylene)-2-(diphenylphosphino)benzenamine under an elimination of MesH. Further reaction of 1 with an excess of S(8) produced a mononuclear Cu(II) complex [o-N═CH… (More)
