Potassium 2-oxoimidazolidine-1,3-diide (POImD) is easily used as an efficient and recyclable catalyst for the synthesis of 2H-indene-1,3-dione derivatives by a reaction between indoles, 2H-indene-1,3-dione and aldehydes at room temperature. All reactions are performed in humid POImD in high to excellent yield during short reaction time. Further, the catalyst can be reused and recovered for several times without loss of activity.
