- Energy efficient Pfitzinger reaction: A novel strategy using a surfactant catalyst
-
A novel energy efficient method for the Pfitzinger reaction is demonstrated, which is catalysed using a surfactant, cetyltrimethylammonium hydroxide. The surfactant nature of the catalyst caused the substrate to be soluble in aqueous media, which enhanced the interaction of the catalyst with the substrate. An increase in the rate of reaction and more than 78% of energy saving were observed under ultrasonic irradiation.

- One-pot synthesis of quinoline-4-carboxylic acid derivatives in water: Ytterbium perfluorooctanoate catalyzed Doebner reaction
-
Ytterbium perfluorooctanoate [Yb(PFO)3] has been proved to be an efficient catalyst for Doebner reaction of pyruvic acid, aldehydes and amines under mild conditions in water to afford quinoline-4-caboxylic acid derivatives with three component one-pot method in good yields. The process is operationally simple and environmentally benign and the catalyst has readily been recycled for several times with consistent activity. Furthermore, a plausible mechanism for this transformation is also presented.
