Abstract: Molybdenum-catalyzed allylic alkylations exhibit excellent chemoselectivity. Carbonyl functional groups like esters and ketones need not be protected. The order of reactivity of a normal alkylating agent like an alkyl bromide and an allyl acetate is inverted compared to the uncatalyzed reaction-an observation that means that an alkyl bromide is compatible. In contrast to palladium-mediated reactions, silicon substituents at the allylic ...
