“…The new chemical shift around 3.5–4.2 ppm, simultaneously, disappearance the peaks of vinylic hydrogens and methylene protons at 2.7 and 5.2–5.4 ppm respectively, it’s suggested the hydroxylation reaction occurring on this system [ 53 – 55 ]. Clearly, the roles of addition Na 2 S 2 O 8 in ML hydroxylation are distinctly different between the presence and absence of the water to the acetonitrile as co-solvent due to increasing the polarity of solvent, the other is to promote Fe 3+ cit-catalyzed hydroxylation of methyl linoleate, addition Na 2 S 2 O 8 effectively improved the catalytic hydroxylation of methyl linoleate to the desired products under the simple conditions with atmospheric air at 80 °C.…”

With the increasing demand for antimicrobial agents and the spread of antibiotic resistance in pathogens, the exploitation of plant oils to partly replace antibiotic emerges as an important source of fine chemicals, functional food utility and pharmaceutical industries. This work introduces a novel catalytic method of plant oils hydroxylation by Fe(III) citrate monohydrate (Fe3+-cit.)/Na2S2O8 catalyst. Methyl (9Z,12Z)-octadecadienoate (ML) was selected as an example of vegetable oils hydroxylation to its hydroxy-conjugated derivatives (CHML) in the presence of a new complex of Fe(II)-species. Methyl 9,12-di-hydroxyoctadecanoate 1, methyl-9-hydroxyoctadecanoate 2 and methyl (10E,12E)-octadecanoate 3 mixtures is produced under optimized condition with oxygen balloon. The specific hydroxylation activity was lower in the case of using Na2S2O8 alone as a catalyst. A chemical reaction has shown the main process converted of plantoils hydroxylation and (+ 16 Da) of OH- attached at the methyl linoleate (ML-OH). HPLC and MALDI-ToF-mass spectrometry were employed for determining the obtained products. It was found that adding oxidizing agents (Na2S2O8) to Fe3+ in the MeCN mixture with H2O would generate the new complex of Fe(II)-species, which improves the C-H activation. Hence, the present study demonstrated a new functional method for better usage of vegetable oils.Producing conjugated hydroxy-fatty acids/esters with better antipathogenic properties. CHML used in food industry, It has a potential pathway to food safety and packaging process with good advantages, fundamental to microbial resistance. Lastly, our findings showed that biological monitoring of CHML-minimum inhibitory concentration (MIC) inhibited growth of various gram-positive and gram-negative bacteria in vitro study. The produced CHML profiles were comparable to the corresponding to previousstudies and showed improved the inhibition efficiency over the respective kanamycin derivatives.

The catalytic synthesis of amides directly from primary alcohols and amines represents an atom-economical and environmentally benign methodology, which produces H 2 as the sole by-product. Over the past few years, several highly efficient metal-based catalytic systems have been developed for this green and sustainable synthetic procedure. This review will focus on the recent advancements and discoveries in this promising and hot research field which may allow possible new insights into catalyst improvement.
