An efficient synthesis of (chiral) alkyl dialkylcarbamodithioates via a CuI‐catalyzed C−S cross‐coupling reaction of (chiral) quaternary ammonium salts and (chiral) dialkylcarbamodithioic acid salts has been developed. C−S coupling products were obtained with extremely high ee values and yields, with enantioenriched arylmethyl trimethylammonium triflates affording the inverse absolute configuration.
