alpha-Bromonitriles, such as 1, 2 or the alpha-bromosulfone 3, undergo a smooth bromine-magnesium exchange with isopropylmagnesium bromide furnishing new functionalized organomagnesium species which react smoothly with various electrophiles like Me3SiCl, Bu3SnCl, allyl bromides, aldehydes, ketones or acid chlorides providing the expected products of type 7, 8 or 9.
