Transition metal complexes containing the bis(trifluoromethyl)nitroxy ligand

Abstract

Stable Ir^III and Pt^II complexes containing the ligand (CF₃)₂NO have been obtained by oxidative addition of the radical (CF₃)₂NO· to Ir^I and Pt⁰ compounds and by metathetical chlorine atom exchange using Hg[ON(CF₃)₂]₂; (CF₃)₂NONa reacts with the cations [M(CO)(MeCN)(PPh₃)₂]⁺(M = Rh or Ir) to afford the Ir^I and Rh^I complexes [M(CO){(CF₃)₂NO}(PPh₃)₂], and with the Pt^IIcations [PtX(CO)L₂]⁺(X = Cl, Br; L = PPh₃: X = Cl, L = AsPh₃) to give the compounds of type [PtX{CO·ON(CF₃)₂}L₂].
