A new method for the synthesis of dithiocarbamates by CuI-catalyzed coupling reaction

A mild, efficient method for the synthesis of aryl and vinyl dithiocarbamates under the Ullmann coupling condition has been developed. It is applicable to both electron-deficient and electron-rich aryl iodides, and even to sterically hindered vinyl bromides. The yields are good to excellent, and the stereoselectivity is satisfactory.
