Abstract An efficient synthesis of symmetrical 2,2-bis(1H-indol-3-yl)-2H-acenaphthen-1-one is achieved via a reaction of acenaphthenequinone and indoles catalyzed by solid superacid SO42−/TiO2 undersolvent-free conditions at room temperature by grinding, which provides an efficient route to the synthesis of symmetrical 2,2-bis(1H-indol-3-yl)-2H-acenaphthen-1-one. This procedure offers several advantages
electrochemical direct bisarylation of carbonyls with indole derivatives to afford the corresponding bis(indolyl)methane (BIM) derivatives is described. The developed protocol is suitable for aliphatic, aromatic, and heteroaromatic aldehydes, which react with various electron-rich and electron-poor indoles to afford the corresponding BIMs in good to excellent yields. Isatin derivatives also underwent
