palladium‐catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium‐catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization
开发了钯催化的卡宾插入C(sp 3)-H键导致吡咯烷。偶合反应可被Pd 0和Pd II催化,具有区域选择性,并显示出宽泛的官能团耐受性。该反应是从重氮羰基化合物开始的钯催化的C(sp 3)-C(sp 3)键组装的第一个例子。DFT计算表明,这种直接的C(sp 3)-H键官能化反应涉及前所未有的一致的金属化-去质子化步骤。
