First row transition metal complexes ofphthalocyanine 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 ofthe catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-01 and 2-cyclohexene-1-one whereas for cyclooctene it is specifically cyclooctene oxide. For cyclohexene oxidation epoxide yield and selectivity is in the order ofMn^ll >Fe^llI> Fe^ll> CO^lI >Cr^III> Ni^ll > CU^ll,while for 2-cyclohexene-1-one production the ability ofthe catalysts are in the order ofNi^ll > CO^lI> CU^ll> Cr^III» Fe^llI> Fe^ll>Mn^ll
