The synthesis of the new halogenated alcohol BrCF2CFClCH2CHICH2OH as a precursor of 4,5,5 trifluoro-4-ene pentanol F2CCFC3H6OH is based on a two-step process. First, the radical addition of iodine monobromide to chlorotrifluoroethylene (CTFE) led to the expected BrCF2CFClI (I) and ICF2CFClBr (II), but also to BrCF2CFClBr (III) and ICF2CFClI (IV), the amount of which determined by NMR depended on the
