Easy Ketimine Formation Assisted by Heteropolynuclear Gold−Thallium Complexes

Treatment of the heterometallic complexes [AuTl(C 6 X 5 ) 2 (L 1 )] (X = Cl ( 1a ), F ( 1b ), L 1 = ethylenediamine) with ketones at room temperature yields stable amine−imine or diimine complexes with the new ligands bound to the thallium centers. Besides their reactivity in solution, both amine complexes 1a and 1b react in the solid state with ketone vapors at room temperature in a few seconds.
