The addition reactions of $alpha$,$alpha$-difluoroiodomethyl n-butyl ketone, α,α-difluoroiodomethyl cyclohexyl ketone, or $alpha$,$alpha$-difluoroiodomethyl phenyl ketone to alkenes were successfully accomplished in good yields in the presence of copper powder. The reaction was also applicable to alkenes containing a variety of functional groups such as ester, trimethylsilyl, or ether group. Acetonitrile was determined to be the best solvent in the present study and the reaction was performed at 55 ${^{circ}C}$ for 15-22 h. This reaction provides a new, efficient and general method for the synthesis of $alpha$,$alpha$-difluoro functionalized ketones.
