[reaction: see text] A combination of CoCl(2) and 1,6-bis(diphenylphosphino)hexane catalyzes a novel three-component coupling reaction of alkyl bromides, 1,3-dienes, and silylmethylmagnesium chloride, yielding homoallylsilanes in good to excellent yields. The reaction involves a radical species from alkyl halides.
