The dipyridine complex of vanadium with N-methylglycine (sarcosinin) / N, N'- dimethylglycine has been synthesized and shows catalytic action in water and H2O2. In particular, the three-dimensional V (V) quadriperoxyl complex 4 K2[V2O2(02)4(CH3NH2CH2COO)].2H2O (1) was synthetically isolated in crystal form. The structure of the new material was characterized by elemental analysis, FT-IR, Raman, NMR, UV-Visible, cyclic voltammetry, thermostatic analysis (TGA) and X-ray crystallography. Furthermore, pH appears to be a critical factor in composition and isolation. The physicochemical characterization of the hybrid material led to the use of compound 1 as a potential benzene hydroxylation catalyst under a set of variable and mild reaction conditions. The products of the catalytic reaction system after identification of an analytical method were identified and quantified with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detector (GC-FID). The results a) are an example of the involvement of hybrid complexes of dipyridine vanadium in the intended transformations of benzene, b) clearly demonstrate the structural and chemical characteristics which justify the development of catalytic action of vanadium in reactions to organic substrates as a basis for action providing immediately available useful substrates.
