Environmentally hazardous and costly metal ions like Os(VIII), Cr(VI) and Ru(III) have been used on a large scale to catalyse organic reactions thereby posing a threat to the environment. Transition metal ions have been used as effective alternatives to catalyse the oxidation of a variety of perfumery alcohols to the corresponding carbonyl compounds. The oxidation of perfumery phenols to quinones has also been studied using inexpensive transition metal ions of the first series. The oxidation was studied using kinetic methods and the effects of alcohol/phenol concentration, ionic strength, solvent composition and temperature of the oxidation rate have been investigated in detail. From the experimental data collected, suitable reaction mechanisms have been suggested for the oxidation of alcohols/perfumes in the presence and absence of transition metal ion catalysts. Aliphatic alcohols, unsaturated alcohols, cyclic and acyclic alcohols have been oxidised using a variety of organic and inorganic oxidants. The phenols, Eugenol and Isoeugenol, found in Indian plants have also been oxidized. India has a large perfumery industry and is home to several indigenous plants from which perfumery alcohols and phenols are extracted.
