AbstractWe have developed deprotonative zincation of 1,3‐dithiole‐2‐thione at the 4‐position. Addition of lithium diisopropylamide to a THF solution of 1,3‐dithiole‐2‐thione containing ZnI2 and LiI generated the corresponding organozinc species. After this zincation, various aryl and acyl groups were installed at the 4‐position by Pd‐catalyzed cross‐coupling reaction with aryl iodides and Cu‐catalyzed acylation with acyl chlorides, respectively.
