Abstract
An effective route to electrosynthesis of nanorods of 3,3-di(indolyl)indolin-2-one derivatives is described in this article. The reaction between various indole and isatin derivatives proceeds in an undivided cell under constant current conditions in CH3CN at room temperature to give nanorods of the 3,3-di(indolyl)indolin-2-ones in excellent yields. A plausible mechanism for this type of reaction is proposed, and the nanostructure of the products has been confirmed by scanning electron microscopy. Direct environment-friendly electrosynthesis of nanosized 3,3-di(indolyl)indolin-2-ones via multi-component condensation of indoles and isatins, which includes high yield, short reaction time, and low temperature are highlighted points that make the method valuable in organic transformations.
