Eight new catalyst precursors with C-s-symmetry and of the general for
mula (C(13)H(8-n)R(n)CR'R '' C5H4)MCl(2) (n = 0, 2; R = Alkyl, Aryl, H
al; R', R '' = H, Alkyl, Aryl; M = Zr, Hf) have been synthesized and c
haracterized by NMR spectroscopy, Complexes 1b-7b and 3c can be activa
ted by MAO and are useful catalysts for the syndiospecific polymerizat
ion of propylene. First analytic results of the various polypropylene
samples are discussed.
