Abstract

Abstract A variety of β-dicarbonyl compounds can be converted to the corresponding unsaturated derivatives in high yields. The process involves reaction of the β-dicarbonyl carbanion with Se metal, followed by alkylation with methyl iodide to form the methylseleno derivative and subsequent oxidative elimination.
