A document type is Article, introducing its new discovery.

The aminoxyl radical (>N-O.) BTNO (benzotriazole-N-oxyl) has been generated by the oxidation of 1-hydroxybenzotriazole (HBT; >N-OH) with a CeIV salt in MeCN. BTNO presents a broad absorption band with lambdamax 474 nm and e 1840 M-1 cm-1, and spontaneously decays with a first-order rate constant of 6.3 × 10 -3 s-1 in MeCN at 25 C. Characterization of BTNO radical by EPR, laser flash photolysis, and cyclic voltammetry is provided. The spontaneous decay of BTNO is strongly accelerated in the presence of H-donor substrates such as alkylarenes, benzyl and allyl alcohols, and alkanols, and rate constants of H-abstraction by BTNO from a number of substrates have been spectroscopically investigated at 25 C. The kinetic isotope effect confirms the H-abstraction step as rate-determining. Activation parameters have been measured in the 15-40 C range with selected substrates. A correlation between Ea and BDE(C-H) (C-H bond dissociation energy) for a small series of H-donors has been obtained according to the Evans-Polanyi equation, giving alpha = 0.44. From this plot, the experimentally unavailable BDE(C-H) of benzyl alcohol can be extrapolated, as ca. 79 kcal/mol. With respect to the H-abstraction step, peculiar differences in the DeltaS? parameter emerge between an alkylarene, ArC(H)R2, and a benzyl alcohol, ArC(H)(OH)R. The data acquired on the H-abstraction reactivity of BTNO are compared with those recently reported for the aminoxyl radical PINO (phthalimide-N-oxyl), generated from H-hydroxyphthalimide (HPI). The higher reactivity of radical PINO is explained on the basis of the higher energy of the NO-H bond of HPI, as compared with that of HBT (88 vs ca. 85 kcal/mol, respectively), which is formed on H-abstraction from the RH substrate.

Application of 850429-61-7, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 850429-61-7, Name is Methyl2-chloro-4-thiazolecarboxylate, molecular formula is C5H4ClNO2S. In a Article，once mentioned of 850429-61-7

Due to the relative stability of the cumyl radical, cumenes and alpha-methyl-styrenes are ideally structured to directly harvest the oxidizing reactivity of O2 and initiate radical chain reactions in catalyst-free conditions. In the absence of additional substrates, these processes can lead to acetophenones. In the presence of substrates, the cumene oxidation process can be intercepted in various chain reactions, affording very simple protocols for functional group oxidation.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 850429-61-7 is helpful to your research., Application of 850429-61-7

A document type is Article, introducing its new discovery., category: thiazole

A series of new benzothiazolium hemicyanine dyes (HC-1, HC-2, HC-3, HC-4, and HC-5 in Scheme 1) were designed and synthesized for sensitization of nanocrystalline TiO2 electrodes by introducing carboxyl, hydroxyl, or sulfonate anchoring groups onto the dyes’ skeletons. A naphthothiazolium hemicyanine with both sulfonate and hydroxyl (HC-6) was also prepared for comparison. The photophysical and photoelectrochemical studies revealed that three kinds of efficiencies, i.e. the fluorescence quenching efficiencies of the dyes by colloidal TiO2, the monochromatic incident photon-to-current conversion efficiencies (IPCEs) for the dye-sensitized TiO2 electrodes, and the overall photoelectric conversion efficiencies (eta) for the dye-sensitized solar cells (DSSCs) based on these hemicyanines, all depended strongly on the anchoring group types and decreased in the order: carboxyl + hydroxyl > carboxyl > sulfonate + hydroxyl, indicating the importance of the dyes’ adsorbing groups for their sensitization effects in DSSCs. The combination of carboxyl and hydroxyl as anchoring groups led to highly efficient IPCEs over a wide spectrum region with the maximum IPCE of 73.6% and a eta of 5.2% under AM1.5 Global simulated light (80 mW cm-2) for the HC-1 based DSSC, which may result from the complex formation between HC-1 and TiO2 and the cathodic shift of the excited state oxidation potential.
