Four seats, five seats and oxidation method of the organic substrate under existing of the metal complex which possesses six seat ligands and the oxidation catalyst which includes the said complex

摘要

Selective oxidation process for organic substrates by contacting said substrates with an oxidant selected amongst hydroperoxides and/or hydrogen peroxide in the presence of a catalyst containing a metal complex of a least one multicoordinating nitrogenated ligand characterized in that the molar ratio metal complex/peroxide is comprised between 1 and 10-10, the temperature is lower than 120 DEG C, and the metal complex has the general formula: [Lx My Xu]z Yq with M a manganese or iron atom in oxidised condition, X a bridge between metals, Y a counter-ion, x and y being /= 1, 0 /= u /= 3, z being the charge of the metal complex and q = z/charge of Y, and L is a ligand having the formula: R1 Ar1 N - (CH2)r - N Ar2 R2, with Ar1 and Ar2 being linear C1 to C6 carbon chains, linked to a nitrogenated heterocycle, R1 and R2 being hydrogen or a C1-C6 alkyl chain optionally connected to a nitrogenated heterocycle, 2 /= r /= 4.
