Abstract

The debromination of α-bromoketones with an easily accessible ionic liquid, 1-methyl-3- pentylimidazolium tetrafluoroborate,[pmIm] BF4 under microwave irradiation has been investigated. By controlling the reaction time gem-α-dibromoketones are selectively debrominated to either monobromo or debromoketones. The α-monobromo-and α- monoiodoketones are dehalogenated while the corresponding chloroketones remain inert ...
