The present invention provides a process for the preparation of organic bromides, by a radical bromodecarboxylation of carboxylic acids with a bromoisocyanurate.

A polyfluoroalkyl allyl compound represented by the general formula:

CF.sub.3(CF.sub.2).sub.n(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.bCH.sub.2CHCH.sub.2[I]

(n:0 to 5, a:1 or 2, b:0 to 3). The polyfluoroalkyl allyl compound is produced by reacting a carboxylic acid allyl adduct represented by the general formula:

CF.sub.3(CF.sub.2).sub.n(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.bCH.sub.2CHICH.sub.2OCOR[II]

(n, a, and b are as defined above, and R: a C.sub.1-C.sub.3 alkyl group) with a transition metal. This method for producing provides a polyfluoroalkyl allyl compound used as a synthetic intermediate for a fluorine-containing alkylsilane compound that can remove free iodine derived from the raw material compound, before a hydrosilylation reaction is performed, without using a metal reagent having a high environmental impact, and that has excellent handling properties.

The present disclosure provides an integrated process for producing trifluoroiodomethane (CF.sub.3I), in three steps: a) reacting a first reactant stream comprising hydrogen (H.sub.2) and iodine (I.sub.2) in the presence of a first catalyst to produce a first product stream comprising hydrogen iodide (HI); (b) reacting the first product stream with a second reactant stream comprising trifluoroacetyl chloride (TFAC) in the presence of a second catalyst to produce an intermediate product stream comprising trifluoroacetyl iodide (TFAI); and (c) reacting the intermediate product stream to produce a final product stream comprising trifluoroiodomethane. (CF.sub.3I).
