Abstract
When α-alkyl substituted β-dicarbonyl compounds were reacted with allylsilanes in the presence of a rhenium catalyst, the allylation of the benzylic carbon center proceeded through the elimination of the β-dicarbonyl unit to form the corresponding alkenes in moderate to good yields. Regarding the reaction with hydrosilane, the reduction of these compounds also proceeded through the elimination of the β-dicarbonyl unit to give the corresponding alkanes.
