Abstract

Thiolato complexes [W(SR)(CF3C2CF3) 2(?5-C5H5)] have been shown to exhibit two basic structures, a bis-alkyne form [W(SR)(CF3C=CCF 3)2(?5-C5H5)] (R = C6F5, Ph, or 4-MeC6H4) and an ?2-vinyl form [WC(CF3)·C(CF3) SR(CF3C=CCF3)-?5-C5H 5] (R = Me, Et, Pri, Prn, PhCH2, or But) shown by X-ray diffraction studies of the isopropyl complex to result from nucleophilic attack of the SR ligand on an acetylenic carbon atom.
