Abstract

Reactions of the ?²-vinyl complex [W {?³-C(CF₃)C(CF₃)SPrⁱ}(CF₃CCCF₃)(?⁵C₅H₅)] with isocyanides RNC give metallacyclopentadiene derivatives [WC(CF₃)C(CF₃)C(CF₃)C(CF₃)(SPrⁱ)(CNR)₂ (?⁵-C₅H₅)] (R = Me, Ph or 4-MeC₆H₄) via coordinatively unsaturated intermediates [WC(CF₃)C(CF₃)C(CF₃)C(CF₃)(SPrⁱ)(CNR)(?⁵-C₅H₅)] isolated and characterised in the case R = 4-MeC₆H₄. The crystal structure of the d² complex [WC(CF₃)C(CF₃)C(CF₃)C(CF₃)(SPrⁱ)-4-MeC₆H₄NC)₂(?⁵-C₅H₅)] has been determined by X-ray methods. The WC₄(CF₃)₄ ring system is approximately planar, with single WC bonds, mean length 2.210(4) Å, and localised CC double bonds. © 1989.
