Abstract
New complexes of the elements of Groups VIIA, VIIIA, and IB of the Periodic Table* with the trisodium salt of tris(m-sulfophenyl)phosphane as a complex ligand. The complexes are used as catalysts for hydrogenations for the water gas reactions, hydrocarbonyls, hydroformylations, oxidations, carbon-carbon cross-linking reactions (e.g. allene/alkine coupling), and additions of secondary amines to carbon-carbon double bonds.
