A novel one-pot three component synthesis of N-(phenylimino)indazole-1-carbothioamides†
Abstract
A novel and one-pot procedure for the synthesis of N-(phenylimino)indazole-1-carbothioamides was reported via three-component condensation of aldehydes, dithizone and dimedone in the presence of [bpy][FeCl4] under solvent-free conditions. This protocol has valuable features of mild and environmentally benign conditions, short reaction times and high yields of desired products.
