摘要：

A highly efficient green protocol for the preparation of bis-indolylmethanes, bis-2-methylindolylmethanes, bis-1-methylindolylmethanes and 3,3'-diindolyloxindole derivatives from the reaction of indoles with various aldehydes and ketones in the presence of cellulose sulfuric acid under solvent-free conditions is reported. The significant features of this procedure are high yields of the products, mild reaction, solvent-free condition and non-toxicity of the catalyst. (C) 2009 Heshmatollah Alinezhad.
