Pd-catalyzed directed ortho C-H amidation of aromatic ketones with both sulfonamides and amides has been accomplished. The use of an electron-deficient Pd complex, Pd(OTf)(2), is crucial for the success of this transformation. Some key intermediates of the reaction, that is, the cyclopalladation complexes of ketones, have been characterized by X-ray crystallography. Experimental analysis of these palladacycles
已经完成了 Pd 催化的芳香酮与磺酰胺和酰胺的定向邻位 CH 酰胺化。使用缺电子的 Pd 复合物 Pd(OTf)(2) 对这种转变的成功至关重要。该反应的一些关键中间体,即酮的环钯化配合物,已通过 X 射线晶体学表征。这些钯环的实验分析以及 N-甲基磺酰胺的实验结果表明,新反应似乎没有通过氮烯中间体进行。新开发的反应可用于合成有用的有机中间体,例如 2- 和 3- 烷基吲哚和 2- 氨基苯基酮。
