Radical polar crossoverCarbanionA metal free generation of carbanion nucleophiles is of prime importance in organic synthesis. Herein we report a photocatalytic approach to the CoreySeebach reaction. The presented method operates under mild redox‐neutral and basefree conditions giving the desired product...
50for the alkene difunctionalizations is substantially less explored. It is noteworthy that an electroreductive radical-polar crossover strategy for the difunctionalization of alkenes has recently been disclosed by Lin51. Afterward, several methods for difunctionalization of alkenes were developed rapidly ...
Mechanistic investigations indicated that this transformation would proceed through a reductive radical-polar crossover pathway. (1) Xiang, H.; He, J.; Qian, W.; Qiu, M.; Xu, H.; Duan, W.; Ouyang, Y.; Wang, Y.; Zhu, C. Molecules 2023 , 28 , 857. (2) Chami, Z.; Gareil, ...

(10) at the C2 position, which might hamper the addition of aryl radical to indole, showed low reactivity. When no substitution was located at C2 position, the desired product11was obtained in 65% with poor diastereoselectivity of 2:1, which indicates that the substituention located at C2 ...
Two methods for effecting radical reactions in an environmentally friendly way are presented: (i) The tetrathiafulvalene (TTF)-mediated radical-polar crossover reaction converts arenediazonium salts to aryl radicals, which have sufficient lifetime to cyclize onto alkenes鈥攖he resulting alkyl radicals ...
