THE FUNCTIONALIZATION OF SATURATED HYDROCARBONS .31. THE FE(PA)(3)- AND [FE(TPA)CL-2]CLO4-CATALYZED OXIDATIONS OF SATURATED HYDROCARBONS BY HYDROGEN PEROXIDE - A COMPARATIVE MECHANISTIC STUDY

摘要

The Fe(pa)(3) and [Fe(tpa)Cl-2]ClO4 catalyzed (pa = picolinic acid, tpa = tris(2-pyridylmethyl)amine) functionalization of saturated hydrocarbons by H2O2 in pyridine/acetic acid follows a common reaction pathway. Regioselectivity studies indicate, that a high valent iron species is responsible for the activation of the alkane. Alkyl hydroperoxides are the precursors for ketone and alcohol formation. Dioxygen provides the oxygen atoms in the alkyl hydroperoxide. [References: 55]
