chemistry. Here, palladium(II)-catalyzed Nu/Nu′-type 1,1-oxamidation and 1,1-diamination of unactivated alkenyl carbonyl compounds followed by amination are described. The distinguishing features of this reaction include the lack of a directing group, good functional group tolerance, and easily operational catalytic reaction conditions. Mechanistic investigations support a unique route involving two consecutive
具有两个亲核试剂的未活化烯烃的催化 1,1-双官能化引起了极大的兴趣,但在合成化学中仍然是一个挑战。此处描述了钯 (II) 催化的 Nu/Nu' 型 1,1-草酰胺化和未活化的烯基羰基化合物的 1,1-二胺化,然后进行胺化。该反应的显着特征包括缺乏导向基团、良好的官能团耐受性和易于操作的催化反应条件。机理研究支持一种独特的途径,该途径涉及此 1,1-双功能化的两个连续核钯。
