A new preparative route to hydrido-platinum(II) complexes, particularly those containing bulky phosphines which are inaccessible by other methods, involves the convenient reaction of phosphines with bis<(2-methoxy-5-cyclooctenyl)chloroplatinum> in methanol.A β-hydrogen elimination mechanism is described, as well as the preparation and use as hydrogenation catalysts of the complexes trans-<(2-CH3O-5-C8H12)Pt(L)Cl> where L=tertiary phosphine.
