Potassium ferrate, a six-valent iron compound, can be easily prepared by oxidizing ferric nitrate with sodium hypochlorite and the subsequent treatment with potassium hydroxide [1]. The use of supported reagent has attracted much attention because of improved selectivity, reactivity and associated ease of manipulation. Oxidation is a fundamental reaction in organic synthesis. Selective protection and deprotection of functional groups is of great importance in multi-step organic synthesis. In continuation of our investigation on organic manipulation, using microwave irradiation in solvent-free condition, we wish to report a solid state oxidation of alcohols to the corresponding carbonyl compounds, oxidative deprotection of trimethyl silyl ethers, THP-ethers and oxidative cleavage of oximes using potassium ferrate supported onto clay under microwave irradiation insolventless systems.
