Abstract
Aminosilane-functionalised spinel ferrite oxide (Fe2O3) magnetic nanoparticles have been synthesised and used as efficient heterogeneous base catalysts for the condensation of aromatic aldehydes with malonitrile and α (or β) naphthole via a three-component reaction under solvent-free conditions at 80°C. Quantitative conversion of the reactants is achieved under mild conditions. Recovery of the catalyst is easily achieved by magnetic decantation. The supported catalyst is reused four times without significant degradation in catalytic activity. Naphthopyrans are polyfunctionalised benzopyran derivatives that have many biological and pharmacological properties.

Abstract
A convenient method for direct oxidative conversion of aldehydes and alcohols into nitriles has been developed by using the inexpensive and environmentally friendly reagent I2/aqueous NH4OAc. The aqueous NH4OAc as a nontoxic cyanide source is more eco-friendly than aqueous ammonia, because gaseous ammonia evaporates easily from aqueous ammonia but not from aqueous NH4OAc.
