Investigation of Catalytic Processes of Thio-Compounds Conversion to Disulfides Using Novel Butyl/Butoxy-Phthalocyaninates of d-Metals

By the nucleophilic substitution of nitro group in 4-nitrophthalononitrile, novel 4-(4-butylphenoxy) and 4-(4-butoxyphenoxy)phthalonitriles were obtained, which were used to synthesize phthalocyanines and complexes with copper, cobalt and zinc. The structures of the compounds obtained were confirmed by FT-IR and NMR (one and two dimensional) spectroscopy, MALDI-TOF mass spectrometry and elemental analysis. The spectroscopic and catalytic properties as well as resistance to heating of the obtained compounds were studied. The compounds investigated showed high thermal resistance in comparison with the known complexes, which determines their profitability. The complexes were found to exhibit high catalytic activity in desulfurization reaction, which, along with high stability, indicates the prospects of their use as catalysts for Thiuram E obtaining.
