Oxidation of unsaturated compounds. III. Oxidation of 3-chlorocrotonic acid. Synthesis of dl-threonic acid. Proof of configuration of the dl-1,2-dihydroxybutyric acids was written by Braun, Geza. And the article was included in Journal of the American Chemical Society in 1930.Recommanded Product: 26340-58-9 This article mentions the following:

Oxidation of 3-chlorocrotonic acid, m. 83°, with Ba(ClO₃)₂ in H₂O containing a little osmic acid, gives 78% of dl-threo-1,2-dihydroxy-3-chlorobutyric acid (I), m. 100°; further oxidation, after removing the Cl with AcOAg, with dilute HNO₃, gives dl-(HC(OH)CO₃H)₃ and a small amount of (CO₃H)₃. I, neutralized with BaCO₃, and treated with Ag₂O, gives 46% of dl-threonic acid, m. 98°; with HNO₃ no trace of mesotartaric acid is found, proving that the treatment with HNO₃ causes no inversion. This acid does not form a lactone under the conditions in which the dl-erythronic acid can be isolated only as a lactone. The proof of the configuration of the dl-1,2-dihydroxybutyric acids (II) is based on the fact that the I may be converted into racemic acid and on the other hand it may be catalytically reduced to the II, m. 74-5°, in 70% yield. This shows clearly that the II, m. 74°, has the same configuration as racemic acid and the other possible II, m. 81.5°, has a configuration corresponding to mesotartaric acid. The assignment of the prefixes “threo” and “erythro” for the acids m. 74.5° and 81.5°, resp., is therefore justified. In the experiment, the researchers used many compounds, for example, (E)-4-Chlorobut-2-enoic acid (cas: 26340-58-9Recommanded Product: 26340-58-9).

(E)-4-Chlorobut-2-enoic acid (cas: 26340-58-9) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: 26340-58-9

Shape Evolution of CdSe Nanoparticles Controlled by Halogen Compounds was written by Meyns, Michaela;Iacono, Fabiola;Palencia, Cristina;Geweke, Jan;Coderch, Mauricio D.;Fittschen, Ursula E. A.;Gallego, Jose M.;Otero, Roberto;Juarez, Beatriz H.;Klinke, Christian. And the article was included in Chemistry of Materials in 2014.Synthetic Route of C18H37Cl This article mentions the following:

Halogen compounds are capable of playing an important role in the manipulation of nanoparticle shapes and properties. In a new approach, the authors examined the shape evolution of CdSe nanorods to hexagonal pyramids in a hot-injection synthesis under the influence of halogenated additives in the form of organic chlorine, bromine, and iodine compounds Supported by d. functional theory calculations, this shape evolution is explained as a result of X-type ligand coordination to sloped and flat Cd-rich facets and an equilibrium shape strongly influenced by halides. Synchrotron XPS measurements and TXRF results show that the shape evolution is accompanied by a modification in the chem. composition of the ligand sphere. The exptl. results suggest that the mol. structure of the halogenated compound is related to the degree of the effect on both rod growth and further shape evolution. This presents a new degree of freedom in nanoparticle shape control and highlights the role of additives in nanoparticle synthesis and their possible in situ formation of ligands. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Synthetic Route of C18H37Cl).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Synthetic Route of C18H37Cl

And the article was included in Sensors and Actuators, B: Chemical in 2022.Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

In this paper, over 20 kinds of tin monoxide (SnO) morphologies are prepared by using a facile solvothermal process. Among all these obtained SnO materials, the shapes with unique morphologies such as bowl-, pompon-, sheet-, hollow frame-like structures exhibit excellent NO₂ gas sensing, photocatalytic degradation, and lithium-ion batteries properties due to their large sp. surface area and more active sites compared with other shapes. For the NO₂ gas sensors properties, these SnO with unique morphologies exhibit excellent sensing performance, including low detection limits (≤ 100 ppb, even reaching 5 ppb), short response and recovery time (< 100 s). Finally, the as-prepared SnO are used as the efficient photocatalysts and lithium-ion battery anode material. These performances have been improved significantly compared with other shaped SnO proposed by other reports. All these advantages indicate the huge application potential of SnO in the field of photocatalysis, gas sensitivity, and lithium-ion battery performance. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride).

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride

And the article was included in European Journal of Medicinal Chemistry in 2021.Formula: C19H15Cl This article mentions the following:

In this study the synthesis and antitrypanosomal activity of 80 compounds I [X = CH, N; R = H, (R)-HO, C₆H₅CH₂O, etc; R¹ = H, HO, C₆H₅CH₂O, etc; R² = H, HO, 2-cyclohexylethoxy, etc; R³ = H, Me, Et, etc; R⁴ = H, H₃C(H₂C)₁₀] based around a core tetrahydroisoquinoline scaffold were reported. A detailed structure activity relationship was revealed, and five derivatives (two of which have been previously reported) with inhibition of T. b. rhodesiense growth in the sub-micromolar range were identified. Four of these I [X = N, R = (R)-HO, R¹ = 4-(4-chlorophenyl)phenylmethoxy, R² = R⁴ = H, R³ = Me; X = N, R = R² = R⁴ = H, R¹ = 4-phenylphenyl, R³ = Me; X = N, R = R¹ = HO, R² = (4-phenylphenyl)methoxy, R³ = R⁴ = H; X = N, R = (R)-HO, R¹ = HO, R² = H, R³ = Me, R⁴ = H₃C(H₂C)₁₀] were also found to have good selectivity over mammalian cells (SI > 50). Calculated logD values and preliminary ADME studies predict that these compounds I are likely to have good absorption and metabolic stability, with the ability to passively permeate the blood brain barrier. This makes them excellent leads for a blood-brain barrier permeable antitrypanosomal scaffold. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Formula: C19H15Cl).

(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C19H15Cl
