Ni‐Catalyzed Thioetherification of Alkyl and Aryl Thiols With Aryl Bromides Under Base‐Free Condition

ABSTRACT A method for Ni‐catalyzed coupling of thiophenols and thiols with aryl bromides is described. The reactions proceed under mild, base‐free conditions and accommodate the coupling of tertiary alkyl thiols, aryl thiols, and cysteine derivatives with aryl electrophiles, yielding alkyl‐aryl and diaryl thioethers in moderate to high yields.
