Convenient synthesis of bis(indolyl)alkanes by dithiocarbohydrazone Schiff base/Zn(ClO4)2·6H2O catalyzed Friedel–Crafts reaction of indoles with imines
Friedel–Crafts reaction of indoles with imines in the presence of dithiocarbohydrazone Schiff base/Zn(ClO4)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.

this study, a library of Schiffbasesderivedfrom aliphatic (Glyoxal) and aromatic (Vanillin) aldehydes with different substitutedaniline compounds. In addition to their complexes with Iron (III) were synthesized. The synthesized compounds were characterized by chemical and physical techniques (IR, 1H-NMR, melting point, color, UV-Visible). The library of the Schiffbases and their complexes were
