Eac. Brussee et al., The N,N'-bis(trimethylsilyl)pentafluorobenzamidinate ligand: enhanced ethene oligomerisation with a neutral V(III) bis(benzamidinate) alkyl catalyst, CHEM COMMUN, (6), 2000, pp. 497-498
The pentafluorobenzamidinate ligand [C6F5C(NSiMe3)(2)](-) is reported, toge
ther with its bis(benzamidinate) vanadium(iii) methyl derivative; the latte
r is considerably more active in catalytic ethene oligomerisation than its
non-fluorinated analogue.
