Oximes derivatives have been vastly used in organic synthesis. In this review, C(sp^(3))-H bond functionalization of oximes derivatives via iminyl radical induced 1,5-hydrogen atom transfer was discussed. According to...Oximes derivatives have been vastly used in organic synthesis. In this review, C(sp^(3))-H bond functionalization of oximes derivatives via iminyl radical induced 1,5-hydrogen atom transfer was discussed. According to the different type of products, this review was divided into three parts: (1) C(sp^(3))-H bond functionalization for C-C bond formation. (2) C(sp^(3))-H bond functionalization for C-N bond formation. (3) C(sp^(3))-H bond functionalization for C-S, C-F bond formation.展开更多
