Conversion of aromatic ketones into π-arylalkanoic acids. Oxidation by thallium(III) and by halogens was written by Higgins, Stanley D.;Thomas, C. Barry. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1982.COA of Formula: C9H9ClO2 This article mentions the following:

The mechanism by which Tl(NO₃)₃ oxidizes aromatic ketones to α-arylalkanoic acids was studied, using PhCOMe as substrate. An organothallium intermediate, probably PhCOCH₂-Tl(NO₃)₂, is a significant feature of this reaction and the key factor influencing the efficiency of this reaction is the readiness with which this species is converted into its acetal. Tl(III) is not a unique reagent for this oxidation; any reagent which can act initially as an electrophile and then as a leaving group is suitable, provided acetal formation is possible. The iodine-AgNO₃ system has several advantages over Tl(NO₃)₃ as it gives high specificity and toxicity problems are eliminated. In the experiment, the researchers used many compounds, for example, Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6COA of Formula: C9H9ClO2).

Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.COA of Formula: C9H9ClO2

Dissociation constants of organic acids was written by Kendall, J.. And the article was included in Med. Vetenskaps. Nobelinst. in 1914.Name: 3-Chloro-5-nitrobenzoic acid This article mentions the following:

The apparatus and method have been previously described (C. A., 6, 3043). K.’s value for H⁺ ion at 25°, Λ₀ = 347.2 was used. The expression m²/(1-m)v = k + c(1-m)/m, (1), where k and c are constants for a particular acid, expresses the results of the previous work. The conductivity of HOAc at 25° was means. from N to 0.0005 N. The value of (k + c(1-m)/m) = K’ increased with the dilution up to v = 16, after which it was 1.84 × 10^-5. HOAc is such a weak acid that the value of the constant c in eq. (1) is negligibly small. For HCOOCH₂CN Λ₀ = 398.2 and K’ = 3.91 to 3.69 × 10^-3 between 0.03 N and 0.0002 N. For KCOOCHCl₂ Λ₀ = 112.9 and K’ for the acid changes with the concentrate from 0.0933 at N to 0.0490 at 0.002 N; for KCOOCCl₃, Λ₀ = 111.2 and K’ for the acid changes from 0.423 to 0.091 between N and 0.002 N. Here the acids are so strong that values of k and c in equation (1) cannot be calculate For trichlorobutyric acid Λ₀ = 376.0, K’ = 0.148 at 0.03 N to 0.0102 at 0.002 N; o-chlorobenzoic acid, Λ₀ = 380.0; K’ = 1.288 to 1.281 × 10^-2 from 0.0006 N to 0.0002 N; o-nitrobenzoic acid, Λ₀ = 379.4, K’ = 6.75 to 6.21 × 10^-2 between 0.03 N and 0.002 N; m,m-dinitrobenzoic acid, Λ₀ = 376.3, K’ = 1.57 × 10^-2; m-chloro-m-nitrobenzoic acid, K’ = 7.48 × 10^-4. Good agreement is found between eq. (1) and the observed values, but the exact theoretical significance of the equation does not seem to be apparent. The value Λ₀ = 380.2 is given for salicylic acid, but the value of K’ does not become constant, even at 0.0002 N, probably on account of the diss. of the second H⁺ ion. For 5-bromosalicylic acid K’ goes through a minimum about 0.002 N, then increases as the dilution proceeds. A similar increase was found at the lower concentrate for 1,2,4-hydroxysalicylic acid, ?-1-2-4-bromohydroxysalicylic acid, 1,2,5-hydroxysalicylic acid and ?-1-2-5-bromohydroxysalicylic acid. In the experiment, the researchers used many compounds, for example, 3-Chloro-5-nitrobenzoic acid (cas: 34662-36-7Name: 3-Chloro-5-nitrobenzoic acid).

3-Chloro-5-nitrobenzoic acid (cas: 34662-36-7) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Name: 3-Chloro-5-nitrobenzoic acid

A series of 2,1-benzisoxazoles, e.g. I (R = Ph, 3-ClC₆H₄, 2-MeC₆H₄, 4-MeOC₆H₄, etc.), was synthesized by cyclocondensation of the corresponding nitrobenzene derivative, e.g. 4-chloronitrobenzene, with arylacetonitriles RCH₂CN, and the substituent effect on the product yield was studied. It is shown that when the aromatic ring of the R fragment contains electron-donating or halogen substituents, the yield of the products depends on the position of these substituents in the aromatic ring. The introduction of electron-accepting substituents partially or completely inhibits the reaction.

Periodic and spatial spreading of alkanes and Alcanivorax bacteria in deep waters of the mariana trench was written by Li, Wen-Li;Huang, Jiao-Mei;Zhang, Pei-Wei;Cui, Guo-Jie;Wei, Zhan-Fei;Wu, Yu-Zhi;Gao, Zhao-Ming;Han, Zhuang;Wang, Yong. And the article was included in Applied and Environmental Microbiology in 2019.Product Details of 3386-33-2 This article mentions the following:

In subduction zones, serpentinization and biol. processes may release alkanes to the deep waters, which would probably result in the rapid spread of Alcanivorax. However, the timing and area of the alkane distribution and associated enrichment of alkane-degrading microbes in the dark world of the deep ocean have not been explored. In this study, we report the richness (up to 17.8%) of alkane-degrading bacteria, represented by Alcanivorax jadensis, in deep water samples obtained at 3,000 to 6,000 m in the Mariana Trench in two cruises. The relative abundance of A. jadensis correlated with copy numbers of functional almA and alkB genes, which are involved in alkane degradation In these water samples, we detected a high flux of alkanes, which probably resulted in the prevalence of A. jadensis in the deep waters. Contigs of A. jadensis were binned from the metagenomes for examination of alkane degradation pathways and deep sea-specific pathways, which revealed a lack of nitrate and nitrite dissimilatory reduction in our A. jadensis strains. Comparing the results for the two cruises conducted close to each other, we suggest periodic release of alkanes that may spread widely but periodically in the trench. Distribution of alkane-degrading bacteria in the world′s oceans suggests the periodic and remarkable contributions of Alcanivorax to the deep sea organic carbon and nitrogen sources. IMPORTANCE In the oligotrophic environment of the Mariana Trench, alkanes as carbohydrates are important for the ecosystem, but their spatial and periodic spreading in deep waters has never been reported. Alkane-degrading bacteria such as Alcanivorax spp. are biol. signals of the alkane distribution. In the present study, Alcanivorax was abundant in some waters, at depths of up to 6,000 m, in the Mariana Trench. Genomic, transcriptomic, and chem. analyses provide evidence for the presence and activities of Alcanivorax jadensis in deep sea zones. The periodic spreading of alkanes, probably from the subductive plates, might have fundamentally modified the local microbial communities, as well as perhaps the deep sea microenvironment. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Product Details of 3386-33-2).
