Perfluoroalkyl iodides, in the presence of a catalytic amount of Ti0 generated in situ, add to alkenes in dimethoxyethane solvent to afford 1-(n-perfluoroalkyl)-2-iodoalkanes in moderate to good yields. 1-Alkenes, 1-alkynes and alkenes containing bromo or ester substituents gave yields of the 1: 1 addition adducts with n-perfluoroalkyl iodides. 1-Alkenes containing ketone or alcohol groups gave low yields of the 1: 1 adduct. Reduction of the 1: 1 adducts ...
