摘要：

The substituted cyclopentadienyl zirconium complex [CP'''2ZrMe2] (1; Cp''' = eta(5)-C5H2-1,2,4(SiMe3)(3)) reacts with tris(perfluorophenyl)borane, B(C6F5)3, in pentane to give the two species [CP'''2ZrMe][MeB(C6F5)(3)] (2) and [CP'''(eta(5)-C5H2-2,4-(SiMe3)(2)-1-eta(1)-SiMe2CH2)Zr][MeB(C6F5)(3)] (3). Complex 3 was characterized by an X-ray structure determination, showing the C-H activation of a SiMe3 group attached to the cyclopentadienyl ligand. Complexes 2 and 3 could be described, respectively, as the active and inactive species which both arise from 1 and B(C6F5)(3) in the cationic polymerization.
