Abstract

Protonolysls of [Cp2ZrCH3(THF)] [BPh4] with tert-butyl mercaptan leads to the (thlolato)zirconocene cation [Cp2Zr(S-t-C4H9×THF)][BPh4] in 79% yield. In addition to the usual spectroscopic methods the complex was characterized by X-ray crystallography (monoclinic, P21/c, a = 10.111 (4) Å, b = 18.6066 (18) Å, c = 19.408 (7) Å, β = 94.31 (2)°, Z = 4, R = 0.036). Structural parameters and THF exchange rates point to a less electrophilic Zr center than In the parent alkyl species. Nevertheless, the center is electrophilic enough to Induce C-S bond cleavage under thermal duress. © 1992, American Chemical Society. All rights reserved.
