Abstract

Addition of [C7H7][PF6] to iron, ruthenium or osmium alkynyl complexes has given eight cationic cycloheptatrienylvinylidene derivatives [M{C C(C7H7)R}(L)2 (η-C5H5)][PF6] (M = Fe, Ru or Os; R = Me, Pr, Ph or C6F5; L = PPh3, L2 = dppm or dppe; but not all combinations). With Fe(C2Ph)(CO)2(η-C5H5), only [Fe(CO)2(thf)(η-C5H5)][PF6] was obtained. Reactions of the new complexes are characterised by loss of the C7H7 group. The NMR spectra and FAB mass spectra are described in detail.
