Herein, an interesting palladium-catalyzed procedure for the direct carbonylative thiomethylation of aromatic amine derivatives with 4-methylthio-2-butanone is developed. Using 4-methylthio-2-butanone as (methylthio) transfer agent, a variety of corresponding thioesters are obtained with moderate to good yields under base-free condition. In addition, good functional group tolerance can be observed
在此,开发了一种有趣的钯催化方法,用于芳胺衍生物与 4-甲硫基-2-丁酮的直接羰基化硫甲基化。使用4-甲硫基-2-丁酮作为(甲硫基)转移剂,在无碱条件下以中等至良好的收率获得了多种相应的硫酯。此外,可以观察到良好的官能团耐受性。
