As the existence of this volume attests, transition metal complexes with phosphine ligands have proven to be useful and versatile catalysts for homogeneous reactions. Recently, binuclear metal complexes, particularly those with bridging phosphine ligands, have begun to attract interest because of their potential as catalysts and because of their novel structural... 

A number of binuclear phosphine-ligand bridged complexes have been shown to function as catalysts or catalyst precursors. Here we review these cases briefly. More detailed coverage of hydrogenation and hydroformyla-tion using rhodium catalysts will appear in the next chapter. In all cases of catalytic activity shown by binuclear complexes, there is a serious question about the true identity of the catalytically active species. As with catalysis begun by metal carbonyl clusters, the possibility exists that a small amount of highly active mononuclear compound is the true catalyst.
