Synthesis and structure of stable chiral AuI complexes with N,N'-diaryl-α-naphthamidinium-N'-[2,3,4,5-tetra(methoxycarbonyl)cyclopentadien-1-yl] ylides
Abstract
Novel N-amidine-functionalized cyclopentadiene gold(i) complexes [C5(CO2Me)4{ArNC(α-C110H7)NAr}]Au(PPh3) have been prepared, and their stable chiral structure with the Au-N bond [2.091(6) Å] and the additional coordination Au‥π-system of the cyclopentadiene ring has been proved by X-ray crystallography and NMR spectroscopy.
