Abstrakt: On the basis of a comparison of the rates of formation of the hydroperoxide, benzaldehyde, and benzoic acid—the basic products of the liquid-phase oxidation of dibenzyl ether in the presence of complexes with the composition Cr2MOPiv6·3L (M=Cr(III), Fe(III), Ni(II), Co(II); L=PPy, γ-Pic, H2O)—it was concluded that, when the sequence of reactions dibenzyl ether→hydroperoxide→benzaldehyde has occurred to a small extent, activation of the substrates occurs at the same catalytic center.
