Abstract: BInuclear metal hydride complexes of scandium, yttrium, lanthanum or a lanthanoid metal are claimed. A binuclear metal hydride complex (I) is of formula (1). M = scandium, yttrium or a lanthanoid metal; R = H, halogen, 1-20C alkyl, 3-10C cycloalkyl, 6-15C aryl or 3-30C organosilyl or two neighboring R groups may form a 4-18C cyclic or heterocyclic group; Z = SiR'2, -CR'2-, -GeR'2-, -SnR'2-, -BR'- or -O-; m = 1 or 2; X = -O-, -S-, -NR''-, -PR''-, -OR''-, -SR''-, -NR''2 or -PR''2; R'' = H, 1-20C alkyl, 3-10C cycloalkyl, 6-15C aryl, 1-10C alkyl-6-10C aryl or 3-30C organosilyl; L = a low mol. wt. Lewis basic organic compound R' = 1-20C alkyl, 1-10C cycloalkyl, 6-15C aryl or 1-10C alkyl- 6-10C-aryl; Independent claims are included for: (i) a process for the preparation of (I) by reacting a mononuclear metal complex (II) of formula (2) in the presence of hydrogen at 1.5-100 bar and 0-100 degrees C; and (ii) a process for the production of (co)polymers by copolymerization of polar monomers in the presence of (I).
