A mild, convenient, and practical one-pot procedure for the direct synthesis of dithiocarbamates has been developed by condensation of amines, CS 2 , and a Michael acceptor, undersolvent-freeconditions at room temperature in good to excellent yields.
Highly efficient one-pot reactions of amines and carbon disulfide with alpha,beta-unsaturated compounds were carried out in water under a mild and green procedure with high yields.
OH<sup>−</sup>/Silica-Mediated One-Pot Synthesis of Dithiocarbamates Under Solvent-Free Conditions
An efficient, versatile, and environmentally benign method for the synthesis of dithiocarbamates under solvent-free conditions is reported. The Michael addition of electron-deficient alkenes with alkyl or aryl amines and CS2 in the presence of OH-/silica in a one-pot three-component reaction protocol gave the corresponding dithiocarbamates in good to excellent yields. This method is suitable for a wide range of amines and a variety of Michael acceptors in solvent-free conditions. The results of the present work show the desired products in excellent yields.
