A novel one-pot three component synthesis of -(phenylimino)indazole-1-carbothioamides

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][FeCl 4 ] under solvent-free conditions. This protocol has valuable features of mild and environmentally benign conditions, short reaction times and high yields of desired products. An efficient novel method have been reported for the synthesis of N -(phenylimino)indazole-1-carbothioamides in the presence of [bpy][FeCl 4 ] under solvent-free conditions.
