Abstract
A catalytic one-step process for the production of CF3I by reacting, preferably in the presence of a source of oxygen, a source of iodine with a reactant of the formula: CF3R where R is —SH, —S—S—CF3, —S-phenyl, or —S—Si—(CH3)3. The catalyst may be a metal salt such as salts of Cu, Hg, Pt, Pd, Co, Mn, Rh, Ni, V, TI, Ba, Cs, Ca, K and Ge and mixtures thereof, preferably on a support such as MgO, BaO and CaO, BaCO3, CsNO3, Ba (NO3)2, activated carbon, basic alumina, and ZrO2.
Claims10
A process for the production of CF3I, the process comprising reacting a source of iodine selected from the group consisting of hydrogen iodide, iodine and iodine monochloride with a reactant selected from the group consisting of those of the formula:
- CF3R
- where R is selected from the group consisting —SH, —S—S—CF3, —S-phenyl, and
- —S—Si—(CH3)3 in the presence of a metal salt catalyst.
