Abstract

full title: Formation of novel ?²-vinyl complexes by nucleophilic attack at co-ordinated hexafluorobut-2-yne: Implications for the stereochemistry of addition and insertion reactions of co-ordinated acetylenes. Crystal and molecular structure of [Mo{SC₅H₄NC(CF₃) ^.C(CF₃)}-(CF₃C=CCF₃)(?-C ₅H₅)] Reactions of Tl(LL) (LL^- = pyridine-2-thiolato, pyrimidine-2-thiolato, or thiazoline-2-thiolato) with the bis-hexafluorobut-2-yne complexes [MCl(CF₃C=CCF₃)_2- (?-C₅H₅)] (M = Mo or W), give products [M{(LL)C(CF₃)^.C(CF₃)}(CF₃C= CCF₃)(?-C₅H₅)] containing a novel ?²-vinyl ligand resulting from nucleophilic attack of LL ^- on an alkyne ligand whereas with [WCl(CF₃C= CCF₃)_2- (?-C₅H₅)] the thallium(I) salt of 2-mercaptopyridine N-oxide unexpectedly promotes cyclopentadienyl group displacement to give the co-ordinatively unsaturated bishexafluorobut-2-yne complexes [W(SC₅H₄NO) ₂(CF₃C= CCF₃)₂] and [W(SC ₅H₄N)(SC₅H₄NO)(CF ₃C=CCF₃)₂]; the structure of [Mo{SC ₅H₄NC(CF₃)^.C(CF₃)} (CF₃C=CCF₃)(?-C₅H₅)] has been determined by X-ray crystallography.
