【 摘 要 】

An eco-friendly and expedient procedure for one-pot synthesis of is-(indolyl)methane derivatives via electrophilic substitution reaction at C-3 position of indole with various aldehydes has been developed by using silica-diphenic acid as a novel heterogeneous catalyst. This method has various promising features such as short reaction time, easy work-up procedure, good yield of products and remarkable activity and selectivity of the catalyst.
