To obtain a rapid, efﬁcient and green synthesis of fulleropyrazoline derivatives, ultrasonic irradiation has been applied to the reaction mixtures containing substituted phenylhydrazones, C60 and PhI(OAc)2. This procedure allowed us to achieve products at room temperature in a good yield and short time without any side product. This convenient procedure will provide a further increase of the diversity within the fullerene derivatives.
