We report a formal method for C−H bond functionalization of amines using dicyanopyrazine-derived photocatalyst. Two types of reactions have been demonstrated, including Michael addition and monofluoromethylation. Under transition-metal free conditions, the α-aminoalkyl radicals are produced through single electron transfer and subsequent deprotonation of C−H bonds, then the functionalized products are formed through later addition of generated radicals to electron-deficient alkenes.

二氰基吡嗪衍生的发色团作为 α-氨基 CH 键官能化的高效光催化剂

我们报告了一种使用二氰基吡嗪衍生的光催化剂对胺进行 CH 键官能化的正式方法。已经证明了两种类型的反应，包括迈克尔加成和单氟甲基化。在无过渡金属条件下，α-氨基烷基自由基通过单电子转移和随后的C-H键去质子化产生，然后通过随后将产生的自由基加成到缺电子烯烃上形成官能化产物。
