Indole Compounds

The synthesis of various N-acetyl-bis-indole compounds has been achieved by one pot reaction of indole and acid chloride in the presence of silica sulfuric acid as a catalyst under microwave irradiation to moderate yields. The reaction has also been studied with different acid chlorides and solvents.
