A highly efficient direct coupling of indole compounds with 1,4-benzoquinones was developed "on water" in the absence of any catalyst, organic co-solvent, or additives. The "on-water" conditions provided the best yields of the corresponding products and the only system to produce bis(coupling) products. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Under anaerobic conditions, indoles with unsubstituted 3-positions react with 1,4-benzoquinone and 1,4-naphthoquinone in acidic solution to give intensely coloured 2-(3-indolyl)quinones in good yields.In the case of 3-methylindole, the reaction with 1,4-n
