A green Hunsdiecker reaction: synthesis of β-bromostyrenes from the reaction of α,β-unsaturated aromatic carboxylic acids with KBr and H2O2 catalysed by Na2MoO4·2H2O in aqueous medium
Abstract
Reaction of α,β-unsaturated aromatic carboxylic acids with KBr and H2O2 in the presence of Na2MoO4·2H2O in aqueous medium affords β-bromo alkenes in high yield.
