The green and efficient procedure for the preparation of substituted bis-indolyl methane via condensation of indole with various aryl aldehydes (3 MCR) in the presence of catalytic amount MFA (Modified Fly Ash; a zeotype catalyst) at reflux temperature in good to excellent yield (85-95%) is reported. This method is utilizing the solvent free condition with the beneficial features such as short reaction time and easy process for isolation. The rate of reactions is found to relay on EDGs and EWGs substituents present on aryl aldehydes at particular positions.
