Unexpected reactions of pentafluorophenylboron compounds with η-cyclopentadienyl(benzamidinato)zirconium derivatives

Abstract
The new base-free compounds [{Zr(η-C5R5)[η-CPh{N(SiMe3)}2]Cl}][B(C6F5)3X]2(R = H, X = Me, CH2Ph or R = Me, X = C6F5*) and [{(η-C5H5)[η-CPh{N(SiMe3)}2](C6F5)}Zr(µ-Me)B(C6F5)3}],* are prepared; the formation of the latter requires the transfer of a C6F5 group from [B(C6F5)4]:* indicates the crystal structure has been determined.
