A series of dibridged diphosphine metal complexes of general formula [5,5′-dppx1-{(η4-C6H7)Fe(CO)2}2-(μ-dppx2)][BF4]2 (x1, x2=p, p (IX); x1, x2=b, b (X); x1, x2=n, n (XI); x1, x2=h, h (XII); x1=p, x2=b (XIII); x1=b, x2=n (XIV); x1=n, x2=h (XV)) containing both metal-metal and ring-ring diphosphine bridges are reported. In the course of the synthetic studies, phosphine transfer reactions (both mono and diphosphine) were observed between a metal bonded phosphine and a sufficiently electrophilic metal carbonyl cation. Phosphine transfer also occurs when normal hydride abstraction reactions are attempted with only stoichiometric amounts of [Ph3C][BF4].
