1552-42-7, Name is Crystal violet lactone, belongs to benzofurans compound, is a common compound. Formula: C26H29N3O2In an article, once mentioned the new application about 1552-42-7.

A series of ruthenium and chromium complexes bearing pH indicators as the eta6-arene ligand, (eta6-X)(MLn)y [X = methyl yellow, crystal violet lactone, phenolphthalein; MLn = RuCp*+, RuCl2(L), Cr(CO)3; y = 1, 2] is prepared and characterized by spectroscopic and crystallographic methods. Of the plural arene rings in the indicators, a specific arene ring can be successfully coordinated to the metal center in a selective manner under appropriate conditions (i.e. use of the precursors of different oxidation states and reaction with the non-protonated and protonated pH indicator). The obtained indicator complexes show halochromic behavior depending on pH as observed for the parent molecules but the transition pH ranges are shifted to the more acidic side because of the attachment of the electron-withdrawing metal fragments, which decrease the basicity of the attached pH indicators.

A key intermediate was obtained as solid through filtration of the reaction mixture of saccharin, chloro(triphenyl)phosphonium chloride, and N, N -diisopropylethylamine (DIPEA) in chloroform. The soluble triphenylphosphine oxide went to filtrate as waste, while the solid was reacted with amines to afford N -sulfonylamidines. In total, 26 N -sulfonylamidine products were obtained in moderate to good overall yields.

Synthetic Route of 652-12-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.652-12-0, Name is Tetrafluorophthalic anhydride, molecular formula is C8F4O3. In a Article，once mentioned of 652-12-0

New highly fluorinated aromatic polyimides based on hexafluoro-2,4- toluenediamine and commercially available dianhydrides (6FDA and ODPA) were synthesized by one-pot high temperature polycondensation in benzoic acid melt. Owing to the CF3 group and fluorine atoms in the meta-linked phenylenediamine fragment, these polyimides combine good solubility in organic solvents including such a low boiling point solvent as chloroform with high glass transition temperatures (330-345 C), thermal and thermooxidative stability (T5 is >500 C). The highly fluorinated polyimide films (hydrogen content is ?1%) exhibit good dielectric properties and low water absorption as well as excellent optical transparency in the UV-vis region (cut-off wavelength is 311 nm for 6FDA-based and 357 nm for ODPA-based polyimides), which is very important for optoelectronic materials.

3-Hydroxyphthalide, C8H6O3, reacts with dibutyltin oxide to give bis{mu 3-oxo-(mu-2-formylbenzoato-O:O?)-(2-formylbenzoato-O) bis[dibutyltin(IV)]}, [Sn4(C4H9)8-(C8H 5O3)4(mu-O)2], in which the four Sn atoms are all five-coordinated to three O and two C atoms arranged at the corners of a distorted trigonal bipyramid. The equatorial Sn – mu3-O distances are in the range 2.039 (2)-2.048 (2) A and are significantly shorter than the axial Sn – mu3-O distances of 2.170 (3) and 2.182 (2) A. The Sn – Ocarboxylate bonds are all axial and have distances in the range 2.204 (3)-2.271 (3) A, which are inversely correlated with the respective C – O bond distances. The mean Sn – C distance is 2.136 (6) A. 3-Hydroxyphthalide undergoes ring opening to give the anion of 2-formylbenzoic acid which bonds to the Sn atoms. The structure of 3-hydroxyphthalide is stabilized by O -H…O hydrogen bonds [O…O = 2.766 (1) A] which link the molecules in a zigzag chain parallel to b.

2,4(1H)-Diarylimidazoles have been previously shown to inhibit hNa V1.2 sodium (Na) channel currents. Since many of the clinically used anticonvulsants are known to inhibit Na channels as an important mechanism of their action, these compounds were tested in two acute rodent seizure models for anticonvulsant activity (MES and scMet) and for sedative and ataxic side effects. Compounds exhibiting antiepileptic activity were further tested to establish a dose response curve (ED50). The experimental data identified four compounds with anticonvulsant activity in the MES acute seizure rodent model (compound 10, ED50 = 61.7 mg/kg; compound 13, ED 50 = 46.8 mg/kg, compound 17, ED50 = 129.5 mg/kg and compound 20, ED50 = 136.7 mg/kg). Protective indexes (PI = TD 50/ED50) ranged from 2.1 (compound 10) to greater than 3.6 (compounds 13, 17 and 20). All four compounds were shown to inhibit hNa V1.2 in a dose dependant manner. Even if a correlation between sodium channel inhibition and anticonvulsant activity was unclear, these studies identify four Na channel antagonists with anticonvulsant activity, providing evidence that these derivatives could be potential drug candidates for development as safe, new and effective antiepileptic drugs (AEDs).

Synthetic Route of 89424-83-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 89424-83-9, 1,3-Dihydroisobenzofuran-5-carbaldehyde, introducing its new discovery.

The first example of a copper-catalyzed cascade reaction of (2-aminophenyl)methanols with aldehydes using the combination of cerium nitrate hexahydrate and ammonium chloride has been developed, leading to a wide range of 2-substituted quinazolines in moderate to excellent yields. The efficiency of this transformation was demonstrated by compatibility with a wide range of functional groups. Thus, the method represents a convenient and practical strategy for synthesis of 2-substituted quinazoline derivatives.
