Design of Bowl‑Shaped N ‑Hydroxyimide Derivatives as New Organoradical Catalysts for Site‑Selective C(sp 3 )−H Bond Functionalization Reactions
TL;DR: A series of new bowl-shaped N -hydroxyimide derivatives has been designed and used as selective organoradical catalysts that exhibit excellent site-selectivity in the amination of benzylic C(sp 3 )-H bonds in aromatic hydrocarbon substrates.
Journal ArticleDOI

Journal ArticleDOI
Rate Acceleration of Solid-Liquid Phase-Transfer Catalysis by Rotor-Stator Homogenizer
TL;DR: In this paper, a rotor-stator homogenizer was used to accelerate phase-transfer reactions in solid-liquid phase transfer reactions, and a considerably high turnover frequency was observed.
Journal ArticleDOI
A Synthetic Route to Sodium α-Aminoalkanesulfinates and Their Application in the Generation of α-Aminoalkyl Radicals for Radical Addition Reactions
TL;DR: Treatment of sodium α-aminoalkanesulfinates with (diacetoxyiodo)benzene easily generated the corresponding α- aminoalkyl radicals under mild conditions, which were then applied in radical 1,2-addition to imines, radical 1-4-add addition to electron-deficient olefins, and radical addition/cyclization to 2-isocyanobiphenyls.
Journal ArticleDOI
Catalytic Asymmetric Alkylation of 3‐Aryl‐Substituted Oxindoles to give 3,3‐Disubstituted Oxindoles under Phase‐Transfer Conditions
TL;DR: An efficient enantioselective method for the construction of all-carbon quaternary stereocenters from 3-aryl-substituted oxindoles via asymmetric phase-transfer alkylation has been developed.
