Abstract
Silica supported-boron sulfonic acid (SBSA) was used as a cheap and mild bronsted acidic in the reaction of indole with aldehydes to afford the corresponding bis(indolyl)methanesin in solvent free grinding and room temperature. The catalyst is also effective in the reaction in good yields. This methodology offers several advantages, such as good yields, reusability of catalyst, short reaction times, simple procedure, and mild conditions. The catalyst can be recovered and reused without loss of activity. The work-up of the reaction consists of a simple filtration, followed by concentration of the crude product and purification.

Highlights
Highlights of this research are listed below:
1) We have developed an efficient, simple, and green-mediated synthesis of bis(indolyl)methane in solvent free, green and room temperature conditions using BSA as a new catalyst for the first time under green condition.
2) Yield of reaction is good to excellent and condition is very simple terms.
