An easily accessible neutral ionic liquid, 1-methyl-3-pentylimidazolium bromide, promoted a one-pot three-component condensation of an amine, carbon disulfide, and an activated alkene/dichloromethane/epoxide to produce the corresponding dithiocarbamates in high yields at room temperature. The reactions are very fast in ionic liquids relative to those in other reaction media. These reactions do not

Different kinds of β-electron-withdraw group substituted ethyl dithiocarbamates (3) were prepared by the conjugated addition of an amine (1) and carbondisulfide to electrophilic alkenes (2) in the presence of anhydrous potassium phosphate under mild condition in good yields. *Visiting scholar from Department of Chemistry, Shangqiu Teachers' College.
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.
