    Abstract: The invention relates to a method for carrying out the transition metal-catalyzed production of polymers having a syndiotactic or predominantly syndiotactic structure from vinyl aromatic monomers. The invention also relates to a method for producing block copolymers from vinyl aromatic monomers and from olefinically unsaturated polar monomers. According to the invention, transition metal compounds of general formula (I) are used in which the substituents and indices have the following meanings: M represents scandium, yttrium, lanthanum or a lanthanoid metal; R''' represents pi -C3 to C20 alkyl; L represents a low-molecular, Lewis-basic organic compound, whereby n1 and n2 = 0 or n1 = 0 and n2 = 1 or n1 = 1 and n2 = 0, and; m represents 1 or 2.

    Abstract: Compounds with a 5-membered unsaturated heterocycle attached by an optionally substituted aminomethyl or phosphinomethyl group to a benzene ring substituted in the o-position with a hydroxy, thiol, amino, alkoxy or alkylthio group. Compounds of formulae (Ia) or (Ib) are new. E1 = O, S, Se, Te, NR, CR2 or PR; E2, E3 = CR, N or P; E4 = N or P; E5 = OH, SH, NHR, OR, SR or NRR; E6 = NH, PH, NR or PR, and at least one of the groups E5 or E6 contains a hydrogen atom; R5, R6 = H, alkyl (linear, branched or cyclic) or aryl; R1-R4 = H, alkyl, aryl, halogen or nitro; R, R = H or alkyl; E2, E3 = O, S, Se, Te, NR, CR2 or PR Independent claims are included for: (1) a method for the production of (Ia) and (Ib) by reacting an aromatic aldehyde with a 5-membered heterocyclic compound substituted with the group -E6H2, followed by reduction of the -CH=E6- group; (2) metal complexes of formula LxMRYz (V); (3) a method for the production of (V) by deprotonation of (Ia) or (Ib) with a base followed by reaction with a metal compound, or by direct reaction of (Ia) or (Ib) with a metal compound; (4) catalytically-active compositions (CAC) comprising: (A) a complex (V) as above; and (B) a component selected from (B1) an organometallic compound, (B2) an organoaluminum-oxy compound and/or (B3) a compound which reacts with complex (A) to form an ion pair; (5) a method for the production of CAC by contacting (A) with (B); and optionally a support material; (6) a method for the (co)polymerization of olefins in presence of CAC as above polymers and copolymers obtained by this method. L = mono- (a) or di-anionic ligand (b) derived from (Ia) or (Ib); E5 = O-, S- or RN- (preferably O-) with E6 = N- or P- (preferably N-) if L is (b), or O-, S- or RN- (preferably O-) with E6 = NR or PR, or OR, SR or NRR' with E6 = N- or P- (preferably N-) if L is (a); M = Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W (preferably Ti, Zr or Hf) if L is (b), or the above metals plus Ni, Pd, Co, Fe, Cu, Ru or Rh (preferably Ti, Zr, Hf, Ni or Pd) if L is (a); R = H, hydrocarbyl (preferably alkyl as above), NR2, OR, halogen or acetylacetonate, preferably halogen or OR; R = H or alkyl; Y = Lewis acid; x = 1 or 2, preferably 1 if L is (b), or 1, 2 or 3 if L is (a); y = 1-4, preferably 2 if L is (b), or 1-4 if L is (a); z = 0-2, preferably 0; R and Y may form a common group, with 2x + y and x + y being the valency of M when L is (b) and (a) respectively.
