A convenient, efficient and green procedure for the synthesis of S-aryl dithiocarbamates has been developed by a simple one-pot condensation of aryl diazonium fluoroborate, carbon disulfide and amine in the absence of any transition metal catalyst in water at room temperature. The reactions of a variety of substituted aryl diazonium fluoroborates, and cyclic and open chain amines, have been addressed. The products are purified by crystallization from ethanol and the process does not involve any hazardous solvent.
