An efficient and clean method to construct CC bonds has been developed via the acylation reaction of acetanilides with benzylic alcohols using tert-butyl hydroperoxide (TBHP) as oxidant catalyzed by palladium acetate in the presence of triflic acid (TfOH). The acylation reactions exhibit excellent reactivities, and up to 95% yield of the corresponding aryl ketone could be obtained under the optimal
通过在三氟甲磺酸(TfOH)存在下用乙酸钯催化的过氧化氢叔丁基酯(TBHP)作为氧化剂,通过乙酰苯胺与苄醇的酰化反应,开发了一种构建CC键的有效且清洁的方法。酰化反应显示出优异的反应性,并且在最佳条件下可获得高达95%的相应芳基酮收率。
