A binuclear Ag(I) complex (1) bridged by two anionic N-heterocyclic carbene (NHC) ligands ferrocenoyl(1-mesitylimidazol- 2-ylidine-3-yl)amide is synthesized. X-ray structure reveals a [Ag...Ag] core spanned by two ligands, each bridging two metals through carbene carbon and amido nitrogen. The neutral complex (1) is highly soluble in a variety of organic solvents and is thermally stable. Complex (1) efficiently catalyses aniline-mediated synthesis of substituted quinolines from 2-aminobenzaldehyde and terminal alkynes.

E/Z equilibrium constants of the ketone anils 6a-s do not depend significantly on the inductive substituent effect. 1H NMR chemical shifts used for configurational classification are also effective for assignments in comparable, isomerically almost pure azomethines 6aa-pp and may be explained by the anisotropic shift model.The 1-azaallyl anions 7 prepared by deprotonation are characterized by 1H NMR spectroscopy.Kinetic and thermodynamic control of this metallation reaction result in different preferential configurations of such anions, the methanolysis of which yields metastable sec. enamines 8 by regio- and stereospecific N-protonation.It is possible to estimate further substituent parameters λd from E/Z equilibria.
