A bis(ortho-amine)aryl-gold(I) compound as an efficient, nontoxic, arylating reagent

A novel strategy for the synthesis of bis(orthoamine)chelated monoanionic bisaminoaryl-metal complexes is presented. This method constitutes the exchange of a. monoanionic, NCN-pincer ligand (NCN = [C6H3(CH2-NMe2)(2)-2,6](-)) between a stable arylgold(I) phosphine, [Au(eta(1)-C-NCN)(PPh3)] (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(PPh3)] as the only coproduct that can be recovered.
