Catalytic properties of these complexes were compared. Reaction orders to H2O2 and catalyst, the effective activation energy were determined. The database (over 100 compounds) of the catalytic properties of 3d metals in the liquid-phase oxidation of dibenzyl ether (DBE) by air oxygen. Adequate 2D QSPR PLS-model Structure-property with high predictive ability was constructed. Structural factors that facilitate or hinder the expression of the above properties studied of metal complexes were identified. Series of new bigeteroaryl derivatives - 2-(2-amino-4-arylthiazol-5-yl)-pyrimidin-4(1H)-ones and 6-methyl-2(1-R-5-phenyl-1H-3-oxyimidazol-4-yl)-pyrimidin-4(1H)-ones - was obtained using products of bromination and nitrosation of 2-(2-oxo-2-aryletyliden)-2,3-dihydropyrimidin-4(1H)-ones.
