Reaction of [MR(CO)3(η5-C5H5)](M = Mo, W; R = Me, CH2Ph, COCF3) with but-2-yne affords either the vinylketone complexes [[graphic omitted])R(CO)2(η5-C5H5)], which on treatment with ligands L form lactone complexes [M(CO)L(η3-{[graphic omitted]Me})(η5C5H5)], or the eight-membered ring complex [[graphic omitted](CO)(η5-C5H5)]; the identity of the products is established by X-ray crystallography.
