Abstract

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.
