Abstract The 1,2-dibromoethane- and KI-mediated α-acyloxylation of ketones is reported in moderate to good yield without the use of transition metals and strong oxidants. Various acids are well tolerated with wide functional group compatibility. An 1,2-dibromoethane- and KI-catalysed reaction mechanism is proposed based on the results of control experiments.
摘要据报道,在不使用过渡金属和强氧化剂的情况下,酮的1,2-二溴乙烷和KI介导的α-酰氧基化反应具有中等至良好的收率。各种酸均具有良好的耐受性,并具有广泛的官能团相容性。根据控制实验结果,提出了1,2-二溴乙烷和KI催化的反应机理。
