Multiple bonds react with the title systems to give 1,2-dichlorocompounds. 1-Acetoxy-2-chlorocompounds are formed as typical byproducts. The stereochemistry of the addition varies from mainly cis to exclusively trans. Simple ketones give α-monochlorketones in good yields.

various experiments. These include screening of reaction conditions, analysis of reactivity and selectivity over diverse ketones, kineticstudy of the reaction of monoacetoxylation and diacetoxylation, density functional theory calculations for estimating the energy and structure, and analysis of natural bond orbitals. Based on the reaction products of the study, the pseudo first-order model is determined
在这里,我们通过各种实验研究了酮的α-乙酰氧基化。这些包括反应条件的筛选、不同酮的反应性和选择性分析、单乙酰氧基化和双乙酰氧基化反应的动力学研究、用于估计能量和结构的密度泛函理论计算以及自然键轨道的分析。根据研究的反应产物,确定伪一级模型为该反应的最佳模型,并且反应中间体的鉴定表明碘是该反应中必需的中间体。此外,动力学研究和理论计算表明,根据酮结构,该反应可能采用不同的机制;然而,在这种情况下,我们重点关注 4- 的 α-乙酰氧基化叔丁基环己酮。基于这些发现,我们提出了碘( III )在α-乙酰氧基化反应中的反应机理和相应的行为描述。
