Copper(II) bromide mediated oxidation of acylated enol and use of the reaction in the synthesis of α,β-unsaturated or α-bromo ketones or aldehydes are disclosed. The method provides an efficient and practical process for manufacturing dehydrohedione (DHH) and many other versatile α,β-unsaturated or α-bromo ketones or aldehydes in large scales to avoid using precious metal compounds.
本发明公开了由
溴化铜(II)介导的酰化烯醇氧化反应,以及利用该反应合成α,β-不饱和或α-
溴酮或醛的方法。该方法为大规模生产脱氢双酮(DHH)和许多其他多功能α,β-不饱和或α-
溴酮或醛提供了一种高效实用的工艺,从而避免了使用贵
金属化合物。
