摘要：

Protonolysis of [Cp2ZrCH3(THF)] [BPh4] With tert-butyl mercaptan leads to the (thiolato)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, P2(1)/c, a = 10.111 (4) angstrom, b = 18.6066 (18) angstrom, c = 19.408 (7) angstrom, beta = 94.31 (2)-degrees, 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.
