Magnetically nano-$CoFe_2O_4$ efficiently catalyzes oxidation of primary and secondary benzylic and aliphatic alcohols to give the corresponding carbonyl products in good yields. The reactions were carried out in an aqueous medium at room temperature in the presence of oxone (potassium hydrogen monopersulfate) as an oxidant. In addition, the catalysts could be reused up to 6 runs without significant loss of activities. Catalyst was characterized by SEM, XRD and IR.

<P>Water was used as an efficient green solvent for the synthesis of sterically congested 1,3,4-oxadiazoles derivatives via a one-pot, three-component reaction of various aromatic carboxylic acids, acenaphthoquinone, and N-isocyanimino-triphenylphosphorane (Ph3PNNC) at a reaction temperature of 20-26 degrees C for 15h. The remarkable features of this green methodology include high yield of products, water as the solvent, short reaction time, operational simplicity, environmentally benign, and the absence of any volatile or hazardous organic solvents.</P>

<P>Reactions of N-isocyaniminotriphenylphosphorane (NICITPP) with 2-oxopropyl-1-benzenecarbothioate in the presence of aromatic carboxylic acids and primary amines proceed smoothly at room temperature (18-26 degrees C) and in neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives in high yields. The reaction progresses smoothly and clearly under mild conditions and no side reactions were observed.</P>
