Reaction of Mn(CO)₅Br with CF₃SAg in CH₂Cl₂ solution gives yellow crystalline [CF₃SMn(CO)₄]₂. However, reaction of Re(CO)₅Br with CF₃SAg under similar conditions gives not only white [CF₃SRe(CO)₄]₂ but also white CF₃SRe(CO)₅; the latter compound is converted to [CF₃SRe(CO)₄]₂ upon boiling in cyclohexane. Reaction of C₅H₅Fe(CO)₂I with CF₃SAg in acetone solution gives red-brown liquid CF₃SFe(CO)₂C₅H₅. Reaction of the π-allyl derivative C₃H₅Fe(CO)₃I with CF₃SAg in CH₂Cl₂ solution gives red liquid CF₃SFe(CO)₃C₃H₅. Reaction of C₅H₅Cr(NO)₂Cl with CF₃SAg in acetone solution gives yellow-brown crystalline CF₃SCr(NO)₂C₅H₅. Reaction of (C₅H₅)₂TiCl₂ with CF₃SAg does not give a CF₃S-Ti derivative. Instead a novel shift of fluorine from carbon to titanium occurs resulting in the formation of yellow (C₅H₅)₂TiF₂. The infrared, nmr, and mass spectra of the new compounds are discussed.
