Solvent free, microwave assisted conversion of aldehydes into nitriles and oximes in the presence of NH2OH · HCl and TiO2
Aromatic aldehydes bearing electron-donating groups are easily converted into their respective nitriles using NH2OH · HCl and TiO 2 under microwave irradiation, while those bearing an electron-withdrawing group give the corresponding oximes.

Hydroxy- or methoxy-substituted benzaldoximes and benzaldehyde-O-alkyloximes as tyrosinase inhibitors
Several benzaldoximes, benzaldehyde-O-ethyloximes, and acetophenone-oximes were synthesized and evaluated as tyrosinase inhibitors by an assay based on tyrosinase catalyzed L-DOPA oxidation. Whereas benzaldoxime itself is only a weak inhibitor, its deriva
