Paper
The new chiral ruthenium bis(bpy) sulfoxide reagent, Δ-cis-[Ru(bpy)2(dmso)Cl]PF6 (100% ee following HPLC resolution) is used to prepare Δ-[Ru(bpy)2(dmbpy)][PF6]Cl in excellent yield (97%) with almost complete retention of absolute configuration (96.8%), as confirmed by X-ray crystallographic studies on a single enantiomer of [Ru- (bpy)2(dmbpy)][PF6]Cl (obtained without resolution or chromatographic methods) and by analysis of the optical properties of both the precursor and product.
