| Abstract: | Treatment of trans-RuCl2(P-P)2] (P-P=4-membered chelate diphosphine) with 2 equiv. of AgOTf in 1,2-dichloroethane gave labile complexes formulated cis-Ru(OTf)2(P-P)2], which readily undergo ligand substitution reactions with neutral or anionic ligands to give cis-Ru(L)2(P-P)2]2+ or RuX2(P-P)2]; these have been characterised by 31P{1H} and 1H NMR spectroscopy, FAB mass spectrometry and (in some cases) X-ray crystallography. |
