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

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

Abstract:

The kinetics of the oxidation of benzaldehyde and para-substituted benzaldehydes by quinolinium chlorochromate in water-dimethylformamide mixtures has been studied under pseudo-first-order conditions at 25?0.2?C. The operation of non-specific and specific solvent-solute interactions was explored by correlating the rate data with solvent parameters through a correlation analysis technique. Both electron-releasing and electron-withdrawing substitutents enhance the rate of oxidation and the Hammett plot shows a break in the reactivity order indicating the applicability of a dual mechanism.

Abstract:

The carbonyl stretching mode in some of the 4- x-benzaldehydes is in Fermi resonance with an overtone of a fundamental which occurs at lower frequency. In general, the unperturbed vC=O frequencies for 4- x-benzaldehydes do appear to correlate with the σp values of the 4- x atom or group. The AN values of the solvents show a pseudo-correlation with the carbonyl and vasym. NO2 stretch vibrations of 4- x-benzaldehyde. However, neither σp nor AN values appear to take into account solute/solvent interactions such as intermolecular hydrogen bonding with the C=O group and with other sites in the mole

In the first step, benzaldehyde and 4-chlorobenzaldehyde separately reacted with thiamine hydrochloride and formed benzoin derivatives (1 and 5). Then, benzoin derivatives separately reacted with urea, thiourea, and guanidine hydrochloride to form different substituted imidazole derivatives (2, 6; 3, 7; and 4, 8), respectively. In the last step substituted imidazole derivatives afforded the final products (F1-F6) upon reaction with benzoyl chloride. Then the molecules were
