Ni‐Catalyzed Cross‐Coupling Reaction: The Direct Synthesis of Symmetrical Disulfanes from Aryl and Primary Alkyl Halides

摘要: A novel Ni-catalyzed cross-coupling reaction is introduced for the direct synthesis of diaryldisulfanes and dialkyldisulfanes from aryl halides primary alkyl at normal atmospheric conditions, respectively. This one-pot domino protocol utilizes only 10 mol% NiCl2 as a catalyst morpholin-4-ium morpholine-4-carbo-dithioate new, stable, solid, odorless sulfurating reagent in presence ethylene glycol cosolvent bidentate ligand dimethyl formamide (DMF) 130°C with good to excellent yields relatively short time reaction.
