the Pd-catalyzed amination of arenes to form N-aryl phthalimides with regioselectivity controlled predominantly by steric effects. Mono-, di-, and trisubstituted arenes lacking a directing group undergo amination reactions with moderate to high yields and high regioselectivities from sequential addition of PhI(OAc)2 as an oxidant in the presence of Pd(OAc)2 as catalyst. This sterically derived selectivity
我们报告了 Pd 催化的芳烃胺化形成 N-芳基邻苯二甲酰亚胺,其区域选择性主要受空间效应控制。在 Pd(OAc) 2 作为催化剂的存在下,连续加入作为氧化剂的 PhI(OAc) 2 后,缺乏导向基团的单、二和三取代的芳烃可以进行中等至高产率和高区域选择性的胺化反应。这种空间衍生的选择性与类似的芳烃乙酰氧基化形成对比。
