Acylation of benzene and toluene with 5-phenyl- and 5-(p-tolyl)isoxazole-3-carbonyl chlorides gave 5-phenyl(or p-tolyl)isoxazol-3-yl phenyl(or p-tolyl)ketones which were reduced to the corresponding alcohols with sodium tetrahydridoborate in propan-2-ol. Selective reduction of the carboxy group in 4,5-dichloroisothiazole-3-carboxylic acid was achieved by the action of BH3, and the aldehyde group in 4-formyl-2-methoxyphenyl 5-arylisoxazole-3-carboxylates and 4,5-dichloroisothiazole-3-carboxylates was reduced to hydroxymethyl group with sodium triacetoxyhydridoborate in benzene. Acylation of the resulting hydroxymethyl derivatives with 5-arylisoxazole- and 4,5-dichloroisothiazole-3-carbonyl chlorides afforded the corresponding esters containing two azole fragments in their molecules.

New discoveries in chemical research and development in 2021, Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, and development of new chemical products and materials. 99-04-7, Name is 3-Methylbenzoic acid, SMILES is O=C(O)C1=CC=CC(C)=C1, in an article , author is ELAZHARY, AA, once mentioned of 99-04-7, HPLC of Formula: https://www.ambeed.com/products/99-04-7.html.

Optimized geometries, harmonic force fields, and dipole derivative tensors were computed for isoxazole and isothiazole with HF, MP2, DFT, and MCSCF methods using the 6-31G** atomic orbital basis set. The ab initio force fields were scaled to form scaled quantum mechanical (SQM) force fields using the experimental fundamental frequencies for isoxazole-d(0) and -d(3) and isothiazole-d(0), -4-d(1), -5-d(1), and -4,5-d(2). The calculated frequencies confirmed the experimental assignment for isothiazole and its isotopomers and showed up possible misassignments for isoxazole and its -d(3) isotopomer. The computed atomic polar tensors were used to calculate the IR absorption intensities. The best agreement between the calculated optimized geometries and IR absorption intensities and the experimental results was obtained with density functional calculations, but the correlation between the scale factors determined for both molecules was worse than those calculated at the MP2 and HF levels. With MP2 the optimized geometries were slightly worse than those at the DFT level, the calculated IR absorption intensities were in excellent agreement with the experimental IR absorption intensities for the in-plane modes but in poor agreement for the out-of-plane modes, and the correlation between the scale factors determined for both molecules was excellent. The HF- and MCSCF-optimized geometries and IR absorption intensities are slightly worse than the density functional results. Although the geometry and the intensity for the in-plane modes are calculated correctly with MP2, the large disagreement of the out-of-plane modes indicates a strong static correlation. The correlation between the scale factors determined with HF was worse than that at the MP2 level but better than that of the density functional and MCSCF calculations.

New Advances in Chemical Research in 2021, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media. 99-04-7, Name is 3-Methylbenzoic acid, molecular formula is C8H8O2, belongs to isothiazole compound. In a document, author is Guillard, J, introduce the new discover, Category: isothiazole.

Premixed ethyl carbamate, thionyl chloride and pyridine (which generate thiazyl chloride, N=SCl) in boiling benzene or toluene convert 2,5- and 2,3,5- substituted furans into 5- acylisothiazoles regiospecifically. The reactions are much faster and generally higher yielding in boiling chlorobenzene with more thionyl chloride and with pyridine or isoquinoline as base. Under the more vigorous conditions, even fully substituted 3-bromofurans give isothiazoles, with the displacement of bromine. Deactivated furans, with electron-withdrawing groups such as ester, cyano, benzoyl and phenylsulfonyl in the alpha -position, react under the more vigorous conditions to give 5- acylisothiazoles with the electronegative group in the 3-position. The ‘activated’ 2-methyl-5-phenyl- and 5-phenyl-2-phenylthio-furans react analogously, with the more electron-releasing group becoming part of the 5- acyl substituent, exclusively or predominantly. These results are explained by initial electrophilic attack of the furan ring to give beta -thiazyl derivative which spontaneously ring-opens and closes to the isothiazole. The X-ray structures of ve of the differently substituted isothiazole compounds are reported. All have very similar patterns of bonding within their isothiazole rings that appear to be independent of the electron-withdrawing or -donating nature of the substituents. Three of the compounds (8a, 8g and 13) have loosely linked chain structures in the solid state, adjacent molecules being connected by combinations of hydrogen bonding and pi-pi stacking interactions.

We report for the first time cyclic phosphine-free head to tail N,N,N pincer-like (pincer complexes mimicking) N-(pyrimidin-2-yl)-1,2-azole-3-carboxamide Pd(II) complexes with deprotonated amide groups as high-turnover catalysts (TON up to 10(6), TOF up to 1.2 x 10(7) h(-1)) for cross-coupling reactions on the background of up to quantitative yields under Green Chemistry conditions. The potency of the described catalyst family representatives was demonstrated in Suzuki-Miyaura, Mizoroki-Heck, and Sonogashira reactions on industrially practical examples.
