资源简介：
The novel group IV metal chelating diamide complexes [(2,6-diisopropylanilido)B(NMe2)B(NMe2)(2,6-diisopropylanilido)]MX2, 7a (M = Ti, X = Cl), 7b (M = Ti, X = Me), and 8 (M =
Zr, X = CH2Ph), have been prepared and characterized by 1H and 13C{H} NMR spectroscopy
and single-crystal X-ray structure analysis (7a). These complexes are active polymerization
catalysts upon combining with the appropriate activator. The catalyst efficiencies, however,
are considerably lower than those of Cp-based catalysts. The molecular weights of the
polymers produced are activator dependent, and the polydispersities were found to be broader
than those observed for Cp-based single-site catalytic systems.
