Electric Literature of 125-20-2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 125-20-2, Name is Thymolphthalein, molecular formula is C28H30O4. In a Conference Paper，once mentioned of 125-20-2

A new method for the separation enrichment of trace Zn2+ using microcrystalline thymolphthalein as an adsorbent was established. The separation enrichment behaviour of Zn2+ and the conditions for the separation quantitatively of Zn2+ with other metal ions were investigated. The possible separation enrichment mechanism of Zn2+ was discussed in detail. The results showed that by controlling pH 10.0, in KBr-diacetydioxime(DMG)-thymolphthalein(TP) system, chelate settlement of Zn(DMG)2 which formed by Zn2+ and DMG was quantitatively adsorbed on the surface of microcrystalline thymolphthalein,and the liquid-solid phases were formed with clear interface, while Cu2+, Bi3+, Al3+, Hg2+ could not be adsorbed. The quantitative separation of Zn2+ from those metal ions was achieved. The proposed method has been successfully applied to the quantitative separation of trace Zn2+ in synthetic water samples with enrichment yield of 93.5%?99.3%.

Application of 41717-32-2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 41717-32-2, Name is 1-Benzofuran-2-carbonitrile, molecular formula is C9H5NO. In a Article，once mentioned of 41717-32-2

2-Benzofuran carboximidamide and various of its substituted derivatives have been tested for analgesic, anti-inflammatory and ulcerigeneous activity. For comparison, the same tests were performed with 2-naphto[2,1-b]furan carboximidamide, some 3-benzopyrancarboximidamides and 2-furan carboximidamide. Most 2-benzofurancarboximidamides show to have interesting analgesic properties. Some of them are also anti-inflammatories. 3-Methyl-5-bromo-2-benzofurancarboximidamide can be compared to aspirin and phenylbutazone as analgesic and anti-inflammatory respectively; no significant ulcerigeneous effect was noted for this compound.

A practical catalytic method for enantioselective addition of an allene unit to aldimines is disclosed. Transformations are promoted by an in-situ-generated B-based catalyst that is derived from a simple, robust, and readily accessible (in multigram quantities) chiral aminoalcohol. A range of aryl-, heteroaryl-, and alkyl-substituted homoallenylamides can be obtained in 66-91% yield and 84:16 to >99:1 enantiomeric ratio through reactions performed at ambient temperature and in the presence of 0.1-3.0 mol% of the chiral catalyst and a commercially available allenylboron reagent. The catalytic protocol does not require strict anhydrous conditions, can be performed on gram scale, and promotes highly selective addition of an allenyl unit (vs a propargyl group). The utility of the approach is demonstrated through development of succinct approaches to syntheses of anisomycin and epi-cytoxazone.

Chemistry is traditionally divided into organic and inorganic chemistry. Product Details of 23932-84-5, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 23932-84-5

Two difluorinated analogues of FPL 64176 (methyl 4-(2-benzylbenzoyl)-2,5-dimethylpyrrole-3-carboxylate) have been synthesized in three steps from 6-fluorophthalide and methyl 2,5-dimethylpyrrole-3-carboxylate. Significant overlap of signals was observed in the aromatic regions of the 1H NMR spectra of these compounds. Using 1H-{1H} and 1H-{19F} NOE difference spectroscopy it was possible to identify and assign all aromatic resonances and, based on the NOEs observed, differentiate between the positional isomers and definitely assign the structure of each.

Application of 59434-19-4, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.59434-19-4, Name is 4-Aminophthalide, molecular formula is C8H7NO2. In a Article，once mentioned of 59434-19-4

Zinc phthalocyanine with PEG-400 was established as a catalytic system for chemo and regioselective reduction of aromatic nitro compounds to corresponding amines. A large range of reducible functional groups such as acid, amide, ester, halogen, lactone, nitrile, N-benzyl, O-benzyl, hydroxy and heterocycles were well tolerated. Direct synthesis of benzotriazole from O-dinitrobenzene was achieved for the first time. The present catalytic system was successfully employed for the reduction of carbonyl and ester compounds to corresponding alcohols and reductive amination of benzaldehydes with primary amines to form corresponding secondary amines. Remarkable advantages of the present catalytic method include low loading of metal, avoidance of toxic ligands and high isolated yields. The catalyst was recyclable up to four times without any loss of selectivity and activity.

652-12-0, Name is Tetrafluorophthalic anhydride, belongs to benzofurans compound, is a common compound. HPLC of Formula: C8F4O3In an article, once mentioned the new application about 652-12-0.

(Chemical Equation Presented) 9,10-Dichlorooctafluoroanthracene (1) was synthesized from commercially available tetrafluorophthalic acid by an optimized solution-phase route. To establish 1 as a synthon for n-type organic semiconductors, the compound was reacted with phenylboronic acid under modified Suzuki-Miyaura coupling conditions to generate octafluoro-9,10- diphenylanthracene (7) in high yield. Cyclic voltammetry and X-ray crystallography indicate that 7 has a stabilized LUMO energy level and exhibits extended pi stacking, which should lead to efficient electron transport in solid-state devices. 1,2,3,4,5,6,7,8-Octafluoroanthracene (2) was also synthesized as a potential n-type building block, but suitable C-C coupling conditions for this compound were not found, and 2 could not be converted into 9,10-dibromooctafluoroanthracene or octafluoro-9,10-diiodoanthracene.
