A palladium-catalyzed oxidative C–H bond functionalization/ortho-acylation of acetanilides using easily accessible aldehyde as the acyl source is described. In the presence of a Pd(TFA)2 catalyst and tert-butylhydroperoxide at 90 °C in general, an array of ortho-acylacetanilides can be afforded in good yields.
描述了使用容易获得的醛作为酰基源的钯催化的乙苯胺的氧化CH键官能化/邻位酰化反应。通常在90℃下在Pd(TFA)2催化剂和叔丁基氢过氧化物的存在下,可以良好的收率得到一系列邻-酰基乙酰苯胺。
