The electrophilic addition of dimethylbromosulfonium bromide to conjugated enones: efficient synthesis of α-bromo enones

Article abstract of DOI:10.1139/v82-322

Dimethylbromosulfonium bromide reacted readily with many enones at 0 deg C or lower to precipitate α-bromo-β-sulfonium conjugated enones.These salts eliminate a proton and dimethylsulfide readily with aqueous potassium carbonate to give excellent yields o
