A Bis( ortho -amine)aryl−Gold(I) Compound as an Efficient, Nontoxic, Arylating Reagent

A novel strategy for the synthesis of bis( ortho -amine)chelated monoanionic bisaminoaryl−metal complexes is presented. This method constitutes the exchange of a monoanionic, NCN-pincer ligand (NCN = [C 6 H 3 (CH 2 NMe 2 ) 2 -2,6] - ) between a stable arylgold(I) phosphine, [Au(η 1 - C -NCN)(PPh 3 )] ( 2 ), and a transition metal halide. This transmetalation results in the quantitative formation of [M(NCN)] organometallic compounds (M = Au III, Ni II, Pd II, Pt II, Ti IV, and Fe III ) and [AuCl(PPh 3 )] as the only coproduct that can be recovered.
