| Zusammenfassung: | A new, convenient and excellent yield procedure for the preparation of bis（indolyl）methanes （BIMs） by Friedel-Crafts reaction of indoles with imines in the presence of dithiocarbohydrazone Schiff base/ Zn（CIO4）2.6H2O as a highly stable, effective and readily available catalyst is described. Moderate to good yields （up to 99% yield） were obtained with both substrates for imine derivatives. This procedure is simple, practical and economic. |
