An efficient sonochemical synthesis of novel fulleropyrazolines through the reaction of [60] fullerene with phenylhydrazones and PhI(OAc)2

To obtain a rapid, efficient and green synthesis of fulleropyrazoline derivatives, ultrasonic irradiation has been applied to the reaction mixtures containing substituted phenylhydrazones, C-60 and PhI(OAc)(2). This procedure allowed products, at room temperature, to be achieved in good yield and in a short time without any side products. This convenient procedure will provide a further increase of diversity within the fullerene derivatives. (C) 2015 Sharif University of Technology. All rights reserved.
