Excellent examples of such compounds are diphosphanes and their derivatives, for which, among many methods of synthesis, the ideal ways to formation of P-P and P-C bonds, due to high selectivity and efficiency, are dehydrocoupling1 and hydrophosphination2 reactions catalyzed by metal complexes. Recently, we have reported the synthesis of the first phosphido complexes of iron stabilized by beta-diketiminato ligand and their catalytic activity in dehydrocoupling of phosphines. All obtained phosphido complexes are active catalysts in formation of diphosphane Ph2P-PPh2 from secondary phosphine Ph2PH. It is worth to emphasize that in these reactions, from not complicated substrate in the presence of small amount of non-toxic and not expensive catalyst, we can obtain diphosphane with high yield where the only by-product is hydrogen.
