Allylic Rearrangements. XXVIII. The Reaction of Butenylmagnesium Bromide with Hindered Ketones

Abstract

Recent studies of the addition reactions of the butenylmagnesium bromide have indicated that the butenyl Grignard reagent is probably best formulated as being exclusively crotylmagnesium bromide. The almost invariable formation of products containing α-methylallyl groups in carbonyl addition reactions has been suggested as due to the operation in the addition process of a six-membered cyclic mechanism.
