Three-component couplings have been realized for efficiently constructing various nitrogen-containing skeletons via C–H activation, where difluorocyclopropenes have been first identified as coupling partners. Many substrates including sp2 and sp3 C–H substrates were well tolerated, furnishing the corresponding products in good yields. Furthermore, a catalyst-dependent reaction was also developed, enabling
已实现三组分偶联,可通过 C-H 活化有效构建各种含氮骨架,其中二氟环丙烯已首次被确定为偶联伙伴。许多底物,包括 sp 2和 sp 3 C–H 底物都具有良好的耐受性,以良好的产率提供相应的产品。此外,还开发了依赖于催化剂的反应,从而能够构建两种不同的框架。这些反应的应用价值在克级实验中得到了证明,催化剂用量低至 1 mol%。
