摘要

A highly efficient, environmentally safe and economic method for selective α- monobromination of aralkyl, cyclic, acyclic, 1, 3-diketones and β-keto esters and α, α- dibromination of 1, 3-diketones and β-keto esters without catalyst is reported using ammonium bromide as a bromine source and oxone® as an oxidant. The reaction proceeds at ambient temperature and yields range from moderate to excellent. Bromination of ...
