A one-pot three-component reaction for the regioselective synthesis of thioarylated imidazoheterocycles from aryl halides and elemental sulfur using copper(I) iodide as a catalyst has been developed. Reactions proceed with high efficiency afford in good yields broad functional group tolerance.
Copper(I) iodide-catalyzed oxidative C(sp(2))-H functionalization of pyridines and isoquinolines for the synthesis imidazo[1,2-a]pyridines 2-phenylimidazo[2,1-a]isoquinolines with vinyl azides under mild aerobic conditions is reported. Good selectivity 3-substituted single isomer formation were observed.
The synthesis of functionalized pyrazolo[1,5-a]pyridines through oxidative [3+2] cycloaddition N-aminopyridines with α,β-unsaturated carbonyl compounds or electron-withdrawing olefins is described. reactions proceed in N-methylpyrrolidone as the solvent under metal-free conditions at room temperature.

Iodine catalyzed C (sp3)-H functionalization of tosylhydrazones with β-enamino esters under visible light irradiation for the synthesis trisubstituted pyrroles has been described. The present method is also applicable to α- substituted yield tetra-substituted pyrroles.
We report a novel and efficient method for the oxidation of benzylic carbons (amines cyanides) into corresponding benzamides using catalytic amount I2 TBHP as green oxidant via C–H bond cleavage carbon under mild reaction conditions. According to literature survey, this is first oxidative amidation benzylamines decyanation benzyl cyanides in one pot metal-free
A facile and efficient route for the synthesis of 2,4-disubstituted imidazoles from benzimidamides vinyl azides through [3 + 2] cyclization under catalyst-free conditions has been described. The method is compatible a broad range functional groups with good to excellent yields.
Abstract Elemental iodine catalyzed decarboxylative sulfenylation (mono‐ or di) of electron‐rich alkoxybenzoic acids using benzenesulfonohydrazides as sulfenylating agent for the synthesis diaryl sulfides under transition metal‐free conditions has been described. The method also works thioarylation indole carboxylic acids. Reactions showed very good functional group tolerance and excellent yields sulfinylated products.
Oxidative esterification of aliphatic primary alcohols with bromide and bromate couple in aqueous acidic medium at room temperature is reported a wide range substrate scope for both cyclic obtained excellent yields products.
Abstract Title compounds such as (III), (V), (VII) and (IX) are formed by reaction of 2‐pyridyl acetates (I) with alkynes alkenes without metal, oxidant, base.
Abstract The title reaction allows the synthesis of a wide range substituted indolizines.
