  • oxidative
  • Ab initio unrestricted Hartree-Fock calculations with a 6-31G* basis set were performed on 2, 6- dimethylphenol (DMP or monomer) and 4-(2, 6-dimethylphenoxy)-2, 6- dimethylphenol (dimer) to gain more insight into the mechanism of the copper-catalyzed oxidative phenol coupling reaction.

  • The kinetics of the copper/N-methylimidazole catalysed oxidative coupling reaction with the C-O coupled dimer of 2,6- dimethylphenol (DMP or monomer), viz. (worldwidescience.org)
  • It was found that oxygen in air had little influence on the oxidative polymerization of 2,6- dimethylphenol (DMP) in the aqueous medium, and potassium ferricyanide was only an oxidant during the oxidative polymerization of DMP. (worldwidescience.org)
  • The influence of varying concentrations and ratios of phenol, base and copper on the copper/N-methylimidazole catalysed oxidative coupling of 2,6- dimethylphenol (DMP) has been studied. (worldwidescience.org)
  • pathway
  • As shown in Fig. ‚Äč Fig.1A, 1A , strain TFA metabolizes tetralin through a meta -cleavage pathway that involves an initial dioxygenation step (catalyzed by the enzymatic complex ThnA1A2A3A4), followed by a dehydrogenation step (catalyzed by ThnB) to produce 1,2-dihydroxytetralin ( 24 ).

  • Degradation of 4-fluorobenzoic acid by strain H1 proceeded via 4-fluorocatechol, which was converted by an ortho -cleavage pathway. (asm.org)
  • The enzyme, studied from phytopathogenic bacteria such as Pseudomonas savastanoi , is involved in a pathway for the production of (indol-3-yl)acetate (IAA), the main auxin hormone in plants. (qmul.ac.uk)
  • degradation
  • Most studies on the bacterial degradation of fluorinated organics describe fluorobenzoic acids, which under aerobic conditions can be converted into the corresponding fluorocatechols ( 3 , 17 , 33 ). (asm.org)
  • The metabolism of these compounds thus proceeds with side chain degradation prior to ring cleavage. (asm.org)

  • oxygenases
  • Amongst oxygenases, a recurrent metal coordination triad is observed, composed by two histidines (His) and one carboxylic acid, coming either from glutamate (Glu) or aspartate (Asp) moieties. (rsc.org)
  • catalyst
  • A kinetic model of NW doping, including the microscopic processes of (1) P incorporation into the liquid catalyst, (2) P evaporation from the catalyst, and (3) P crystallization in the Si NW, quantitatively explains the results and shows that suppression of the reservoir effect can be achieved when P evaporation is much faster than P crystallization.

  • Chalcone is then isomerized to naringenin by chalcone isomerase which is oxidized to eriodictyol by flavonoid 3'- hydroxylase and further oxidized to taxifolin by flavanone 3-hydroxylase. (wikipedia.org)
