Abstract: The influences of monosubstitution at phenyl rings in a series of T(R-P)PFe(Ⅲ)Cl(R=o,m,p-Me,MeO,Cl,Br,I,NO2, o-t-Bu,p-t-Bu,o-NH2,Et,i-Pr)on the biomimetic catalytic monooxygenation of cyclohexane with PhIO were studied.The yields of cyclohexanol were increased by the electron-with drawing substituents Rin these catalysts T(R-I)PFe(Ⅲ)Cl.Afair linear correlation between the yield of cyclohexanol and para substituent constant σpis presented as:lgYR/YH=3. 2σp-0. 03. The steric effect of all ortho substituents in T(R-P)PFe(Ⅲ)Cl increased the yield of cyclohexanol sufficiently.

Key words: T(R-P)PFe(Ⅲ)Cl, Cyclohexane, Monooxygenation, Substituent effect
