methyl salicylatenegative temperature dependenceozonideA theoretical study on the reaction mechanism of methyl salicylate (MeSA), a green leaf volatile organic compound with OHradical and ozone, has been carried out using density functional theory methods using B3LYP, M06-2X and MPW1K func-tionals ...
Mechanism of the salicylate hydroxylase reaction 1.|The spectral natures of chemically- and photochemically-reduced salicylate hydroxylase (salicylate, NADH: oxygen oxidoreductase (1-hydroxylating, 1-decarboxylating)) from Pseudomonas putida have been investigated.

Mechanism of the anthranilate synthetase reaction: Evidence against an intramolecular hydrogen transfer The mechanism of the anthranilate synthetase reaction was studied using chorismic acid specifically labeled with 14C and 3H and the partially purified enzyme from Salmonella typhimurium. The third hydrogen ...
The mechanism is not understood and it may be that a 1,3,5-triazine intermediate is involved. Thus, propionitrile trimerizes when heated under pressure without any catalyst to give 2,4,6-triethyl-1,3,5-triazine (659) and this can be converted subsequently into 2,6-diethyl-5-methyl...
structure of alkenes. The purpose of this paper is to find out the reaction mechanism of this rare FC reaction and understand the origin of the reaction selectivity. Figure 1 The Friedel-Crafts reactions of N,N-Dimethylaniline and corresponding products (5aand6aare the main products in the expe...
Lipids that contain fatty acidester linkagescan undergohydrolysis. This reaction is catalyzed by a strong acid or base. Saponification is the alkaline hydrolysis of the fatty acidesters. The mechanism of saponification is: Nucleophilic attack by the hydroxide ...
The mechanism of this technique is to crosslink or otherwise covalently tie the blocking oligos to one another to permanently remove them from interfering. For example as shown in FIG. 6, an upstream probe is blocked with a blocking oligo having a hairpin-forming 5' nucleotide extension with ...
Differential spectrophotometry was applied to peudo-first-order hydrolysis of methyl salicylate. Thus, the values of the measured quantity at t=oo and t=0 were eliminated in calculation of the rate coefficient. Results obtained by this method were compared statistically with those obtained from the...
MechanismThree reductones, 2,3-dihydroxy-4,4-diphenyl-2,5-cyclohexadien-1-one(11), 3,4-dihydroxycoumarin (35), and 3,4-dihydroxyspiro[5.5]undecan-3-en-4-one (64), were prepared and subsequently reacted with superoxide anion radical(O-2(.-)), generated from KO2 and 18-crown-6 ...
The forward reaction proceeds at the S{dollar}sb1{dollar} 0-0 energy by either a triplet or vibrationally excited ground state mechanism. This reaction was found to not be photochemically reversible.; Heavy atom matrices are known to increase rates of spin-forbidden processes. The phosphorescence...
