Abstract

Thermolysis of the η2-vinyl complex [W{η3-C(CF3)C(CF3)SBut}(CF3C[triple bond, length half m-dash]CCF3)(η5-C5H5)] gives the η3-ethenethiolato derivative (E)-exo-[W{η3-SC(CF3)[double bond, length half m-dash]C(CF3)H}(CF3C[triple bond, length half m-dash]CCF3)(η5-C5H5)], which undergoes concomitant exo→endo and E→Z isomerisation to give (Z)-endo-[W{η3-SC(CF3)[double bond, length half m-dash]C(CF3)H}(CF3C[triple bond, length half m-dash]CCF3)(η5-C5H5)], thus providing evidence for a ring-flip mechanism in metal-promoted alkene isomerisations.
