摘要
In catalyst systems based on rhodium (Rh) complex compounds with diphosphine ligands, the ligands are organoammonium diphosphine-carboxylates, -sulphonates or -phosphonates of formula (I); in which R1 = a carboxylate (-COO-), sulphonate (-SO3-), phosphonate (-PO32-) or 2-aminoethane bisphosphonate Ä-NH-CH2-CH(PO32-)2Ü group; R2 = linear alkylene with 1-8C, 2-6 C alkylene containing oxygen, 3-10 C cycloalkylene or a group of formulae (II), (III), (IV) or (V); at least one of a, b, c, d, e, f, g, h, k, l = 1, otherwise 0; x = 0 or 1; R3, R4 = 4-26 C alkyl, optionally substituted 6-10 C aryl or 6-10 C cycloalkyl or benzyl and R3 may also = hydrogen (H).
