A green and efficient regioselective dehydrative Friedel‐Crafts arylation of trifluorinated 3‐indolyl(2‐thiophenyl) methanols with 2‐substituted indoles, catalyzed by DBSA (dodecylbenzenesulfonic acid) in water is described. This simple and atom‐economical protocol features a unique regioselective 1,8‐addition, operational simplicity, mild conditions, excellent functional group compatibility, and environmental
