description

A series of new titanocene phosphanes 3–6 have been prepared by replacing both chloride atoms at the titanium atom of the complexes [TiCl2(η5-C5H5){η5-C5H4(CH2)2PR2}] (1: R = Ph; 2: R = Cy) by sodium fluoride or sodium benzoate in two-phase systems. Treatment of these new metalloligands with the binuclear complex [(p-cymene)RuCl2]2 affords the targeted titanocene difluoride and titanocene dibenzoate bimetallic ruthenium complexes 8–11. The first chiral Ti–Ru bimetallic complex 12 bearing a binaphthyloxy ligand at the titanium centre has been synthesised in this way. In each series, an X-ray crystal structure has been determined.
