New discoveries in chemical research and development in 2021, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 2107-69-9, Name is 5,6-Dimethoxy-2,3-dihydro-1H-inden-1-one, SMILES is C1=C2C(=CC(=C1OC)OC)C(CC2)=O, in an article , author is Lo Presti, Leonardo, once mentioned of 2107-69-9, COA of Formula: https://www.ambeed.com/products/2107-69-9.html.

3-Diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda(6),2-thiazete-4-carbonitrile (DTC) is a synthetic compound that exhibits a significant similarity with)beta-sultamic drugs. Its core chemical moiety is an uncommon four-membered thiazete-1,1-dioxide heterocycle. Former crystallographic investigations carried out at room temperature on different DTC polymorphs and a chemically related compound showed a very unusual structural feature: within the conjugated -N-C=N-SO2- system, the formally single N-C bond is, on average, 0.018 angstrom shorter than the formally double N=C bond. In this work, the charge density distribution of DTC has been explored by both single-crystal X-ray diffraction at T = 100(2) K and quantum mechanical simulations, with the aim of gaining insights into the subtle interplay between structure, electron delocalization, and crystal field polarization effects. To this end, both local and nonlocal topological descriptors provided by the Quantum Theory of Atoms in Molecules have been employed. Topological and structural changes of crystalline and in vacuo DTC have been related to the smaller or larger importance of resonance forms in the -N-C=N-SO2- moiety. A rationale for the mentioned C-N/C=N bond length inversion is found in terms of the large DTC dipole moment enhancement occurring in the crystal, which stabilizes highly polar resonant forms that exploit more favorable electrostatic interactions with neighboring molecules. In turn, this causes a significant electronic rearrangement within the molecule that results in an unusual and counterintuitive bond length alternation pattern. Possible implications from the viewpoint of the accurate in silico modeling of crystal structures are discussed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Rhodium(II)-catalyzed decomposition of fluorinated diazo diketones in the presence of isothiazole-3(2H)-one 1,1-dioxides offers a chemoselective and useful tool for O-functionalization of their C=O groups by interaction with transient fluorine-containing Rh-II-diketocarbenoids. The resulting O-alkylimidates of isothiazole 1,1-dioxides, bearing (trifluoromethyl)acetyl groups, easily react with traces of H2O giving rise to stable hydrates of the perfluoroacetyl groups. No O -> N isomerization of O-alkylimidates (similar to the Lander-Chapman rearrangement) was observed under the reaction conditions studied.

This is only the third example of a crystal structure containing a 2,1-benzisothiazole ring system. Bond lengths in the isothiazole ring of the title compound suggest much less double-bond character than observed in the other two known structures. The molecule is essentially planar and packs in the crystal with the benzisothiazole rings stacked in the [100] direction.

New research progress on 2107-69-9 in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 2107-69-9, Name is 5,6-Dimethoxy-2,3-dihydro-1H-inden-1-one, formurla is C11H12O3. In a document, author is Vicini, Paola, introducing its new discovery. Category: isothiazole.

2-Heteroarylimino-5-benzylidene-4-thiazolidinones, unsubstituted or carrying hydroxy, methoxy, nitro and chloro groups on the benzene ring, were synthesised and assayed in vitro for their antimicrobial activity against Gram positive and Gram negative bacteria, yeasts and mould. The antimicrobial activity of the 2-benzo[d] thiazolyl-and of the 2-benzo[d] isothiazolyl-imino-5-benzylidene- 4-thiazolidinones is, on the whole, lower in comparison with the high activity detected for the derivatives of the 2-thiazolylimino5- benzylidene-4-thiazolidinone class. Nevertheless most of the benzo[d] thiazole analogues display good inhibition of the growth of Gram positive bacilli and staphylococci, including methicillin-resistant Staphylococcus strains. Among the 2-benzo[d] isothiazole analogues a few derivatives show a strong and selective activity against bacilli. Moreover, it is worth noting that the replacement of the thiazole nucleus for the benzo[d] thiazole bicyclic system in the parent 2-(benzo[d] thiazol-2-ylimino) thiazolidin-4-one leads to significant antifungal properties against both yeasts and moulds, properties not shown by the analogous 2-thiazolyl-and 2-benzo[d] isothiazolyl-imino) thiazolidin-4-ones. The structure-activity relationship of 33 analogues possessing the 2-heteroarylimino-4- thiazolidinone structure is analysed through QSAR models. (C) 2008 Elsevier Ltd. All rights reserved.
