Abstract
Beta-substituted allylsilanes are synthesized in a one-step process from readily available starting materials by the reaction of a specific carboxylic acid ester or acid anhydride with a specific alkoxy group-containing Grignard reagent in an organic solvent. The resulting allylsilanes are useful as allyl transfer reagents for electrophilic reagents such as ketones, carboxylic acid chlorides, etc.
