Abstract
Tetrafluoroethylene and hexafluorobut-2-yne react with RuCl(NO)L2(L = PPh3, PMePh2, PMe2Ph) to form the complexes [R[graphic omitted]F2(Cl)(NO)L2] and [R[graphic omitted](CF3)(Cl)(NO)L2] respectively; the phosphine ligands have a relative trans-configuration. Chlorotrifluoroethylene and hexafluoropropene react with RuCl(NO)(PMe2Ph)2 to form adducts in which the phosphine ligands have a relative cis-configuration. Iodine adds trans to RuCl(NO)(PMePh2) to form Rul2Cl(NO)(PMePh2) which isomerises in solution. Nitrosyltris(triphenylphosphine)iridium reacts with CF3CCCF3 to form di-µ-hexafluorobut-2-enylene-bis[cis-triphenylphosphine(nitrosyl)iridium(I)], whereas tetrafluoroethylene and hexafluoroacetone form [I[graphic omitted]F2(NO)(PPh3)2] and [I[graphic omitted](NO)(PPh3)]. The ruthenium hexafluorobut-2-yne complexes undergo ring-opening reactions with CF3CO2H to form vinyl complexes.Keywords
