A series of zirconocene complexes of formula Cp2ZrMe2-nLn where Cp = C5H-5, Me = methyl, L = pyrazolyl, bis(N,N′-phenylformamidinato), or substituted aryloxide and n = 1,2, were synthesized by reaction of Cp2ZrCl2 and Cp2ZrMe2 with LiL or HL, respectively. The structures of Cp2Zr(2,6-OC6H3Me2)2, Cp2Zr(2,4,6-OC6H2Me3)2 and Cp2ZrMe{CH(NC6H5)2} were determined by single crystal X-ray diffraction. The complexes demonstrate appreciable activity for ethylene polymerization when used as cocatalysts with methylaluminoxane and dimethylanilinium tetrafluorophenylborate.
