1-Bromo-1,2,2,2-tetrafluoroethyl(phenyl)mercury

Abstract

[42201-75-2] C8H5BrF4Hg (MW 457.62) InChI = 1S/C6H5.C2BrF4.Hg/c1-2-4-6-5-3-1;3-1(4)2(5,6)7;/h1-5H;; InChIKey = BXFMDGTYDIIWJC-UHFFFAOYSA-N (excellent source of tetrafluoroethylidene, :CFCF3; cyclopropanates alkenes; inserts into SiH bonds; reacts with CS bonds) Physical Data: mp 121–122 °C. Solubility: sol THF, benzene, dichloromethane. Analysis of Reagent Purity: spectroscopic data: IR, NMR (1H and 19F).2 Preparative Method: prepared in 65% yield by reaction of PhHgCl with CF3CHFBr in dry THF in the presence of MeONa–MeOH.2, 3 Purification: recrystallization from hexane (colorless prisms). Handling, Storage, and Precautions: flame-dried glassware and an atmosphere of dry nitrogen are used for the reactions. Organomercury(II) compounds should be carefully handled and skin contact and inhalation should be particularly avoided. All reactions must be conducted in a well-ventilated hood.
