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...

Tandem Polar/Radical Crossover Sequences for the Formation of Fused and Bridged Bicyclic Nitrogen Heterocycles Involving Radical Ionic Chain Reactions, and... It is demonstrated that phosphorylated forms of 尾-nitro alcohols provide an excellent means of entry into 尾-(phosphatoxy)alkyl radicals on ...
(E1/2Ox = +0.63 V vs. SCE in DMF)55leads to the corresponding radical anion 4CzIPN•−and the radical cation DIPEA•+. The reduced 4CzIPN•−undergoes a single-electron reduction of aryl bromide (ArBr)1, producing the [ArBr]•−radical anionIand regenerating the ...
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 ...

we report a novel strategy to achieve a visible-light-induced spirocyclizative remote arylcarboxylation of nonactivated arenes including naphthalenyl-and phenyl-bearing aromatics with CO_(2) under mild conditions through a radical-polar crossover cascade(RPCC).This reductive dearomatization protocol ...
