1-BROMO-2-BUTANONE Chemical Properties,Usage,Production

Chemical Properties

colorless to light yellow liquid

Uses

1-Bromo-2-butanone (bromomethyl ethyl ketone) was used as a potential regulatory site-directed reagent for the residue C221 on pyruvate decarboxylase. It was also used as a reagent for aromatic bromination with sodium hydride in DMSO and in a microwave-assisted preparation of fused heterocycles.

Synthesis

Using methyl 3-oxopentanoate as the starting material, the key intermediate is obtained via chlorination and dealkylation reactions with a yield exceeding 70%. Subsequently, bromination yields 1-bromo-2-butanone with an overall yield exceeding 50%.
