ABSTRACT

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