  hen络合物催化的烯醇乙酸酯与醇的偶联反应

  摘要：

  在催化量的complex络合物例如ReBr（CO）5的存在下，烯醇乙酸酯与醇的反应以中等至良好的产率产生了相应的酮和醛。有人建议，醚（一种分子间脱水产物）的制备是反应的第一步。

  When benzylic and allylic alcohols were treated with enol acetate in the presence of a catalytic amount of a rhenium complex, ReBr(CO)5, the carbon-carbon bond formation of the alcohols and enol acetate smoothly proceeded to give the corresponding ketones and aldehyde in moderate to good yields. For the reaction of allylic alcohols, γ,δ-unsaturated carbonyl compounds were obtained in good yields. When

  在催化量的complex络合物ReBr（CO）5存在下，用乙酸烯醇酯处理苄醇和烯丙基醇时，醇和乙酸烯醇酯的碳-碳键形成过程顺利进行，得到相应的酮和醛。中等至良好的产量。对于烯丙基醇的反应，以良好的产率获得了γ，δ-不饱和羰基化合物。当使用醚代替醇作为烷基化剂时，在反应中利用了醚上的两个烷基部分。

  4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides undergoes Heck reaction using 2- or 3-subtituted allylic alcohols. With these sterically congested alkenes, the selective formation of β-aryl ketones was observed when appropriate reaction conditions were used. The influence of the functional group on the aryl bromide and of the base on the selectivity is remarkable. With several

  The reaction of enol acetates with alcohols in the presence of a catalytic amount of a rhenium complex, such as ReBr(CO)5, produced the corresponding ketones and aldehydes in moderate to good yields. It was suggested that the preparation of an ether, an intermolecular dehydrated product, was the first step of the reaction.
