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.
Claims7
A complex compound comprising a central atom selected from the group consisting of elements of Groups IB, VIIA, and VIIIA of the IUPAC Periodic Table, said compound containing a trisodium salt of tris(m-sulfophenyl)-phosphine as a complex ligand, excluding a reaction product of bis(1,5cyclooctadiene)nickel with said salt, said compound being of the formula
- L.sub.w.sup.1 L.sub.x.sup.2 M.sub.y [P(C.sub.6 H.sub.4 --m-SO.sub.3 Na).sub.3 ].sub.z
- wherein L.sup.1 and L.sup.2 are individually ligands which, in addition to said salt, are bound to said central atom, M is said central atom, w, x, y, and z are integers, w and x are 0 to 7y, y is 1 to 6, and z is .ltoreq.4y.
