N2 - Nucleophilic attack of phosphines, phosphites, and t-butyl isocyanide (L) on the bis-hexafluorobut-2-yne complexes [WBr2CO(CF3C-CCF3)2] and [MX(CF3C=CCF 3)2(?-C5H5)] (M = Mo, W; X = Cl, SC6F5 : M = W; X = SC6H4Me-p) occurs at an acetylenic carbon atom to give 1:1 adducts shown by X-ray diffraction studies to contain a metal-stabilised 1-3 dipolar vinyl ligand L+C(CF3)·C-(CF3) co-ordinated in an ?2 manner to the metal centre.
