A new simple and efficient one pot transformation of various aliphatic carbonyl compounds to the corresponding dibromoalkenes is described. A wide range of hydrazones of aldehydes and ketones, prepared in situ, were easily converted into dibromoalkenes by treatment with carbon tetrabromide in the presence of CuCl. The reaction proceeds under mild conditions to give the target products in good to high yields.
描述了一种新颖、简单且高效的一锅法转化,将多种脂肪族羰基化合物转变为相应的二溴烯烃。通过碳四溴化物在CuCl存在下的处理,现场制备的醛和酮的脒类化合物可以轻松转化为二溴烯烃。该反应在温和条件下进行,能够以良好至高产率得到目标产物。
