catalytic oxidation

The crown ether or polyglycol additives to transition metal catalysts improve both the performance indicators, such as cyclohexane conversion, selectivity of target products, and the sustainability indicators of the oxidation process. It has been shown that the effect of the organic additives on the sustainability indicators is primarily due to a significant (up to 14.3%) increase in the selectivity of target cyclohexane oxidation products.

The AFM technique was used to research the possibility of the supramolecular structures formation due to H-bonds based on Ni(Fe)(acac)_n-systems, that are catalysts of alkylarens oxidations and also models Ni(Fe)ARD dioxygenases: {M(acac)_n+L²+L³} triple systems (M=Ni^II, Fe^III , L² = NMP (NMP = N-methyl-2-pirrolidone), L-histidine, L³ = PhOH, L-tyrosine), n = 2, 3).

The polymeric complexes of porous iron phosphates (NH₄)₄Fe₃ ^II(OH)₂F₂[H₃(PO₄)₄] (1), (C₃H₁₂N₂) Fe^II ₆(H₂O)₄[B₄P₈O₂₃(OH)₈] (2), and {[Fe^II(H₂PO₄)₂-(μ4,4'-bipy)(H₂O)]·H₂O·(4,4'-bipy)} (3) were successfully tested towards oxidation of cyclohex-2-enol.
