This project consistes of two independent parts. The first part describes oxidation of alcohols to aldehydes with methyltriphenylphosphonium dichromate(MTPPDC) in the presencs and absence of bismuth chlorid in dichlorometan as solvent. MTPPDC has been used for oxidation of alcohols under solvent-free conditions and microwave irradiation as a novel and efficient reagent. Also thiols have been oxidized to corresponding disulfides whit high yield in dichloromthan solvent. Products have been identified by Mass Spectroscopy, 1 H-NMR, IR analysis and their melting point or boiling points. In the second part of this study a new reagent for reduction of carbonyl compounds is reported. Sodium borohydride is a mild reagent and is mostly used for the reduction of aldehydes and ketones in protic solvents. Tetramethylammonium borohydride is useful reagent for reduction of carbonyl compounds. Some advantages of this reagent are : Selective reduction of aldehyde in presence of ketone, fast reaction and straight forward extraction of products. Products have been identified by Mass Spectroscopy, 1 H-NMR, IR and their melting point or boiling points.
