Oxidations of various hydrocarbons and alcohols with in situ generate zinc dichromate trihydrate in the presence of metal ion catalysts like silver and copper were examined. Naphthalene, anthracene, phenanthrene, cyclohexane and toluene dissolved in minimum amount acetic acid by in situ generate zinc dichromate trihydrate in the presence of traces of Ag(I) catalyst: substrate ratio (1: 70 to 1: 300) and Cu(II) catalyst: substrate ratio (1: 60 to 1: 250) under microwave irradiation. All the synthesized containing Cu (II) catalytic system gave higher yield as compare to Ag (I) catalytic system. Phenanthrene was oxidized in 9-Fluorenone instead of phenanthraquinone to get the benzylic rearrangement.
