Montmorillonite K10-supported ZnCl2is an efficient and environmentally friendly catalyst. Reactions of aromatic aldehydes with indole catalyzed by montmorillonite K10-ZnCl2 afforded bis(indol-3-yl)- methanes in 66%~97% yields within 2~8 min by grinding. This method provided several advantages such as simple work-up procedure, shorter reaction time, milder conditions and environmental friendliness.

Key words: montmorillonite K10-ZnCl2, bis(indol-3-yl)methane, synthesis, grinding
