Potassium Carbonate → HCID 15171501, compound

Participants

Reaction Steps

A mixture of (3-bromo-2-oxobutyl)triphenylphosphonium bromide (30 g) in ethyl acetate (150 ml), tetrahydrofuran (50 ml) and water (150 ml) was adjusted to pH 10 with potassium carbonate. The separated organic layer was washed with brine and dried over magnesium sulfate. Evaporation of the solvent gave a residue, which was triturated with diisopropyl ether and collected by filtration to give (3-bromo-2-oxobutylidene)triphenylphosphorane (24.27 g).
