Abstract:
The substrate-specificities of benzyl alcohol dehydrogenase and benzaldehyde dehydrogenase, encoded by TOL plasmid pWW0 of Pseudomonas putida mt-2, were determined. The rates of benzyl alcohol dehydrogenase-catalysed oxidation of substituted benzyl alcohols and reduction of substituted benzaldehydes were independent of the electronic nature of the substituents at positions 3 and 4. Substitutions at position 2 of benzyl alcohol affected the reactivity of benzyl alcohol dehydrogenase: the velocity of the benzyl alcohol dehydrogenase-catalysed oxidation was lower for compounds possessing electron

Abstract:
Iron phthalocyanines tetra substituted with either electron-donating n-hexyloxy or electron-withdrawing n-hexylsulfonyl substituents were prepared and tested as oxidation catalysts for benzyl alcohol, 4-bromobenzyl alcohol, 4-methylbenzyl alcohol and 4-tert-butylbenzyl alcohol. Oxidation reactions were performed at room temperature in acetonitrile, acetone, ethanol, toluene, and the best result was obtained in acetonitrile. Oxidation of alcohols using tert-butyl hydroperoxide as an oxidant in the presence of these iron(II) phthalocyanines resulted in the production of corresponding benzaldehyd

Treatment of alkoxy-substituted o-(pivaloylaminomethyl)benzaldehydes under acidic conditions resulted in the formation of the regioisomeric aldehydes and/or dimer-like products. Detailed NMR studies and single-crystal X-ray measurements supported the structure elucidation of the compounds. DFT calculations were also carried out to clarify the reaction mechanism, and to explain the observed product distributions and structural variances in the dimer-like products. Studies on the transformation of unsubstituted o-(pivaloylaminomethyl)benzaldehyde under similar conditions were presented as well.

Camphor has been using widely, however, Pinene has not. Therefore, Pinene has a great potential. Starting from α-pinene, we have prepared a class of new N-substituted amino alcohols, in which the same site of amino and hydroxyl groups has been unambiguously established. In the studies of asymmetric synthesis, these newly created N-Substituted Amino alcohols are used as catalysts in t

Abstract Products of the condensation reaction between morpholine or cyclohexylamine and benzaldehydes have been used extensively as volatile inhibitors of atmospheric corrosion, as well as components of lubricant compositions, biocides and preservatives in automotive cooling liquids and fuels. In this study, we examined the relationship between the electronic structure and inhibition performance of the compounds in an atmospheric corrosion test. The condensation products have significantly lower vapor pressure than parent amines, resulting in longer residence times of inhibitor species at a m
