Preparation and properties of ZnBr(CF3)*2L - a convenient route for the preparation of CF3I

Article abstract of DOI:10.1016/0022-1139(93)02937-A

ZnBr(CF3)*2L (L=DMF, CH3CN) can easily be prepared by the reaction of CBrF3 with elemental zinc in better than 60percent yield.The reaction of ZnBr(CF3)*2DMF with iodine monochloride in DMF solution yields pure CF3I in better than 70percent yield via an ecologically less damaging reaction pathway than the decarboxylation route using silver or mercury trifluoroacetate.
