C–C bond-forming reactions using Katritzky salts, their deaminative allylation remains a challenge. Inspired by the metallaphotoredox-catalyzed allylic substitution regime, here, we report the deaminative allylation of Katritzky salts via cobalt/organophotoredox dual catalysis. This cross-electrophile coupling enables regioselective allylation using a variety of allylic esters, overcoming the substrate
尽管使用 Katritzky 盐在 C-C 键形成反应方面取得了快速进展,但它们的脱氨基烯丙基化仍然是一个挑战。受金属光氧化还原催化的烯丙基取代方案的启发,在这里,我们报告了通过钴/有机光氧化还原双重催化对 Katritzky 盐进行脱氨基烯丙基化。这种交叉亲电偶联能够使用多种烯丙基酯进行区域选择性烯丙基化,克服了已报道协议的底物限制。机理研究表明,π-烯丙基钴配合物作为介导 C-C 键形成的亲自由基物质参与其中。
