First row transition metal complexes of phthalocyanine are employed as catalysts for the oxidation of cyclohexene and cyclooctene using iodosylbenzene and pentafluoroiodosyl benzene. The catalysis was performed in dichloromethane: methanol:water (80:18:2) solvent mixture. The products of the catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-ol and 2-cyclohexene-1-one whereas for cyclooctene it is specifically cyclooctene oxide. For cyclohexene oxidation epoxide yield and selectivity is in the order of MnII > FeIII > FeII > CoII > CrIII > NiII > CuII , while for 2-cyclohexene-1-one production the ability of the catalysts are in the order of NiII > CoII > CuII > CrIII > FeIII > FeII > MnII .
