A series of isoxazolo[60]fullerenes has been prepared in one pot from aldoximes under microwave irradiation. Several donors and acceptors were used as substituents. The absorption and emission spectra of these compounds in polar solvents suggest a weak charge-transfer interaction between the oxygen atom of the isoxazoline moiety and the C(60) cage, as well as a stronger interaction between the donor

Microwave as a green, rapid and effective procedure has been applied to the synthesis of fulleropyrazolines/fulleroisoxazolines. The reaction mixtures containing substituted phenylhydrazones/oximes, C60 and PhI(OAc)2 allowed to achieve products at room temperature in a good yield and short time without any side product.

In this research, a green, easy, and effective solvent-free procedure for the synthesis of heterocyclic fullerene derivatives has been achieved via 1,3-dipolar cycloaddition reaction of C60, substituted arylhydrazones/oximes, and PhI(OAc)2 under grinding as a simple physical-mechanical method. This approach does not involve any hazardous organic solvent and has various advantages including design of

In this research, an efficient comparison between conventional, grinding and sonication methods for the synthesis of fulleroisoxazolines was investigated. Compared to the conventional methods, ultrasound procedure showed several advantages including mild reaction conditions, high yields, short reaction times and environmental friendliness.

strategies are not amenable to CPP rings that lack heteroatoms. Here, we report the synthesis of two [2]rotaxanes in which a [10]CPP ring binds to a central fullerene bis-adduct and is prevented from dethreading by the presence of two bulky fullerene hexakis-adduct stoppers. The final step in the rotaxane synthesis is surprisingly efficient (up to ca. 40% yield) and regioselective because the fullerene
