N2 - 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] 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.
