The Schmidt reaction of aromatic aldehydes using a substoichiometric amount (40 mol %) of triflic acid is described. Low catalyst loading was enabled by a strong hydrogen-bond-donating solvent hexafluoro-2-propanol (HFIP). This improved protocol tolerates a broad scope of aldehydes with diverse functional groups and the corresponding nitriles were obtained in good to high yields without the need for aqueous work up.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 27550-59-0, name is 5-Hydroxyisobenzofuran-1,3-dione, introducing its new discovery. name: 5-Hydroxyisobenzofuran-1,3-dione

The modification of 3?-((2-cyclopentyl-6,7-dimethyl-1-oxo-2,3- dihydro-1H-inden-5-yloxy)methyl)biphenyl-4-carboxylic acid (BINA, 1) by incorporating heteroatoms into the structure and replacing the cyclopentyl moiety led to the development of new mGluR2 positive allosteric modulators (PAMs) with optimized potency and superior druglike properties. These analogues are more potent than 1 in vitro and are highly selective for mGluR2 vs other mGluR subtypes. They have significantly improved pharmacokinetic (PK) properties, with excellent oral bioavailability and brain penetration. The benzisothiazol-3-one derivative 14 decreased cocaine self-administration in rats, providing proof-of-concept for the use of mGluR2 PAMs for the treatment of cocaine dependence.

A formal [4+2] cycloaddition of alpha,alpha?-dichloro-ortho-xylenes with various alkynes has been developed using a low-valent cobalt catalyst. The transformation has a wide substrate scope and high functional-group tolerance and led to 1,4-dihydronaphthalenes. The formed cycloadducts were easily aromatized with MnO2 under air. A mechanistic investigation suggests that the transformation proceeds through a benzyl cobaltation of alkyne, not the classical Diels-Alder reaction of ortho-quinodimethanes. This methodology provides a straightforward and streamlined access to linearly expanded pi-conjugated aromatics. Simple, but powerful: The title reaction leads to 1,4-dihydronaphthalenes with a wide substrate scope and high functional-group tolerance. Mechanistic investigation supports a benzyl cobaltation of alkyne, not the classical Diels-Alder reaction of ortho-quinodimethanes. This methodology provides a straightforward access to linearly expanded pi-conjugated aromatics.

Novel 3-acetoacetylaminobenzo[b]furan derivatives having a modified triene system at the 3-position were synthesized starting with 3-aminobenzo[b]furans. The enol isomers, 3-[(3-hydroxybul-2-enonyl)amino]benzo[b]furans (1), of the 3-acetoacetylaminobenzo[b]furans were obtained as stable isomers owing to formation of a hydrogen bonding between the enol hydroxyl group and the amidocarbonyl group. The planarity of the C-2 substituent through the C-3 side chain suggested the existence of a modified conjugational triene system in the enol compound. Cysteinyl leukotriene 1 and 2 receptor antagonistic activities for these compounds were evaluated. 2-(4-Cyanobenzoyl or ethoxycarbonyl)-3-[(2-cyano-3-hydroxybut-2-enonyl)amino]benzo[e]furans (15g, 15o, 15u) were moderately active.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C8H2F2O3. Introducing a new discovery about 18959-30-3, Name is 4,5-Difluorophthalic Anhydride

Phenylethynyl containing imide-silanes were prepared from aminoalkyl and aminoaryl alkoxy silanes and 4-phenyletbynylphthalic anhydride in toluene to form the imide in one step or in N-methyl-2-pyrrolidinone (NMP) to form the amide acid intermediate. Controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes were prepared in NMP from aromatic dianhydrides, aromatic diamines, diamines containing pendent phenylethynyl groups and aminoaryl alkoxy silanes. The phenylethynyl containing imide-silanes and controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes were used to improve the adhesion between phenylethynyl containing imide adhesives and inorganic substrates (i.e. metal). Hydrolysis of the alkoxy silane moiety formed a silanol functionality which reacted with the metal surface to form a metal-oxygen-silicon (oxane) bond under the appropriate reaction conditions. Upon thermal cure, the phenylethynyl group of the coupling agent reacts with the phenylethynyl functionality of phenylethynyl containing imide adhesives and becomes chemically bonded to the matrix. The resultant adhesive bond is more durable (i.e. hot-wet environmental resistance) than adhesive bonds made without the use of the coupling agent due to covalent bond formation between the phenylethynyl containing imide-silane coupling agent or the controlled molecular weight pendent phenylethynyl amide acid oligomers terminated with aminoaryl alkoxy silanes and both the metal substrate and phenylethynyl containing imide adhesives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C8H2F2O3, you can also check out more blogs about18959-30-3

Chemistry is traditionally divided into organic and inorganic chemistry. name: Benzo[b]furan-2-carboxaldehyde, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4265-16-1

A conformational study of formyl and acetyl derivatives of benzofuran provides evidence that in the case of 2- and 7-derivatives the E,Z-conformational mixture is solvent dependent, the Z-form prevailing in solvents with higher polarity.The presence of the same substituents in the 3- and 4-position gives compounds with predominantly Z-conformation and no change is caused by solvents.These results show an interestingly different behaviour by carbonyl derivatives of benzofuran with respect to the same benzothiophene derivatives.The conformational analysis was carried out by the n.m.r. method by employing (1)H and (13)C chemical shifts, long-range proton-proton coupling constants, and lanthanide-induced shifts (LIS) simulation.For the derivatives substituted in position 7, the LIS method is not a suitable approach for the determination of the conformer populations since, in solution, a chelate is formed where bonding of Eu to the oxygen atoms of the carbonyl and of the heterocyclic ring stabilizes the Z-form.A quantitative approach for determining the relative conformer populations of benzofuran-7-carbaldehyde was set up by statistical manipulation of long-range proton-proton coupling constants, proton chemical shifts, and the classical of dielectrics.
