1-Hexenesulphonic acid sodium salt as catalyst for green synthesis of bis(indol-3-yl)methanes was described. The reaction of indole with various aldehydes in water using ultrasound irradiation at ambient temperature for appropriate time using 1-hexenesulphonic acid sodium salt furnish the desired product in good to excellent yield. Utilization of aqueous medium, simple reaction conditions, isolation, and purification makes this manipulation very interesting from an economic and environmental perspective.
1-己烯磺酸纳盐作为绿色合成双（吲哚-3-基）甲烷的催化剂。在环境温度下，使用超声波辐射，将吲哚与各种醛在水中反应适当的时间，使用 1-己烯磺酸纳盐作为催化剂，可以得到所需的产物，产率良好到优秀。从经济和环境的角度来看，利用水相介质、简单的反应条件、分离和纯化使得这种操作非常有趣。
