Synthesis, the electronic properties and efficient photoinduced electron transfer of new pyrrolidine[60]fullerene- and isoxazoline[60]fullerene-BODIPY dyads: nitrile oxide cycloaddition under mild conditions using PIFA
electroactive units, have been synthesized and characterized. Their photophysical and electrochemical properties have been studied in solution by comparing with the reference compounds BDP and [60]fullerene. Both BODIPY-C60 derivatives strongly absorb visible light and by photoexcitation at the BDP unit, these dyads undergo photoinduced electron transfer affording the corresponding charge-separated

oxime, imine and carbonyl compounds through alcohol oxidation in the presence of H2O2 and/or O2 have been developed by a melamine-Mn(III) Schiff base complex supported on Fe3O4@SiO2 Cl nanoparticles, named as Fe3O4@SiO2@Im[Cl]Mn(III)-complex nanocomposite, at room temperature. Direct oxidation of alcohol to carboxylic acid was performed using the catalyst in the presence of molecular O2 at room temperature

Participation of ‘activated DMSO’ in the one-pot transformation of aldehydes to nitriles has been described by reacting aldehydes with NH2OHËHCl in DMSO in the absence of any added base or catalyst. The method is applicable to access a wide range of aromatic, heterocyclic, and aliphatic nitriles, in which only water is a byproduct. A straightforward and practical procedure is demonstrated on a multigram scale.
