Abstract

Reactions between [M(?5-C5H5)SR 1(CO)3] (M = W; R1 = Me, Et, or Pri) and hexafluorobut-2-yne (hfb) involve initial attack at sulphur and carbonyl ligands to give [[graphic omitted]R1)(?5-C 5H5)(CO)2] which undergo stepwise rearrangement to co-ordinatively unsaturated acetylene complexes [M(?5-C 5H5)(SR1)(CO)(hfb)]; the latter (M = Mo or W, R1 = C6F5) undergo associative CO substitution reactions with phosphines and phosphites (L) yielding complexes [M(?5-C5H5)(SR1)(hfb)L].
