Amberlyst-15 as a Highly Efficient and Reusable Catalyst for Direct C-S Bond Formation: Synthesis of Barbituryl Carbamodithioates

The C-S bond formation reaction has been described by the reaction of Bromo-barbituric acid with ammonium aryl dithiocarbamates in the presence of Amberlyst-15 as a reusable catalyst in aqueous medium. The mild reaction conditions, easy product isolation and good to high yields, are the major advantages of present protocol.
