In this research, a nano-inorganic composite of CuO/NiO is prepared by co-precipitation method as an efficient recyclable nanocatalyst for the regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles in water. The catalyst was characterized by several techniques such as the field emission SEM (FESEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric anal. (TGA), x-ray fluorescence, inductively coupled plasma at. emission spectroscopy (ICP-OES), and brunauer-emmett-teller (BET) surface area anal. The regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles was carried out from reaction of various benzyl halides or alkyl halides with Ph acetylene and sodium azide in water under reflux condition in high yields. The CuO/NiO nanocatalyst can be simply recovered and reused 6 runs without a significant slight in activity. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Application of 620-19-9).

1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) 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.Application of 620-19-9

Intramolecular reactions of N-nitrenes: oxidation of 3-amino-2-(arylalkyl)quinazolin-4(3H)-ones was written by Atkinson, Robert S.;Malpass, John R.;Woodthorpe, Katherine L.. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1982.Synthetic Route of C9H9ClO2 This article mentions the following:

Oxidation of quinazolines I (R = OMe; R¹ = H, OMe; R² = NH₂; n = 2) with Pd(OAc)₄ in CH₂Cl₂ at room temperature gave I (same R, R¹, n; R² = H) (II) and the diazepines III (R = H, OMe; R¹ ≠ R² = H, OMe) via the corresponding N-nitrene intermediates. On oxidation under analogous conditions I (n = 2, R = H, R¹ = OMe; n = 1, R ≠ R¹ = H, OMe; R² = NH₂) gave only the deamination products II. Azepine formation involves electrophilic aromatic substitution by the nitrene on the aromatic ring via a 7-membered transition state. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0Synthetic Route of C9H9ClO2).

Substituent effects in substrates on activation parameters in the bimolecular nucleophilic reactions in solution was written by Vlasov, Vladislav M.. And the article was included in New Journal of Chemistry in 2010.Recommanded Product: Ethyl 4-chloro-3-nitrobenzoate This article mentions the following:

Changes of the activation parameters, ΔH^≠ and ΔS^≠, in the S_N2, S_NAr and acyl-transfer reactions with charged and neutral nucleophiles in various solvents were correlated with σ constants of the substituents in the aromatic ring of the substrates. The resultant δΔH^≠ and δΔS^≠ reaction constants are linearly related for variations of substituents at the substrate. Correlation of δΔH^≠ vs. δΔS^≠ allows one to estimate the contribution of changes of the internal enthalpy, δΔH^≠_int, to the enthalpy reaction constant, δΔH^≠, which gives a single linear dependence on the Hammett ρ reaction constants for all bimol. nucleophilic reactions. The deviations from dependence of δΔH^≠_int vs. ρ can be interpreted in terms of changes of the transition state structure or reaction mechanism. The results obtained show that the substituent effects in the substrates and nucleophiles on the charge development in the transition state are governed by the magnitude of δΔH^≠_int. In the experiment, the researchers used many compounds, for example, Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2Recommanded Product: Ethyl 4-chloro-3-nitrobenzoate).

Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2) 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. 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).Recommanded Product: Ethyl 4-chloro-3-nitrobenzoate

A series of ethacrynic acid (2-[2,3-dichloro-4-(2-methylidenebutanoyl)phenoxy]acetic acid) (EA, Edecrin) containing sulfonamides linked via three types of linkers namely 1,2-ethylenediamine, piperazine and 4-aminopiperidine was synthesized and subsequently evaluated in vitro against HL60 and HCT116 cancer cell lines. All the EA analogs, excluding two derivs, showed anti-proliferative activity with IC_50s in the micromolar range (less than 4 uM). Three derivatives I–III were selected for their interesting dual activity on HL60 cell line in order to be further evaluated against a panel of cancer cell lines (HCT116, A549, MCF7, PC3, U87-MG and SKOV3) as well as on MRC5 as a normal cell line. These compounds displayed IC₅₀ values in nanomolar range against A549, MCF7, PC3 and HCT116 cell lines, deducing the discovery that piperazine or 4-aminopiperidine is the linker’s best choice to develop EA analogs with highly potent anti-proliferative activities own up to 24 nM. Besides, in terms of selectivity, those linkers are more suitable offering safety ratios of up to 63.8.

In this study ten benzothiazole derivatives bearing the amide moiety were designed, synthesized and evaluated for their antibacterial activity and possible mode of action.

The present study provides us two active compounds (A07 and A10) with a membrane perturbing mode of action, and an intracellular mode of action due to binding with DNA along with potent activity against clin. relevant pathogens E. coli and S. aureus.

Catalytic reduction of organic halogen compounds was written by Rosenmund, Karl W.;Zetzsche, Fritz. And the article was included in Berichte der Deutschen Chemischen Gesellschaft in 1918.Synthetic Route of C4H5ClO2 This article mentions the following:

Colloidal Pd protected with gum arabic or palladinized BaSO₄ is an efficient catalyst in the removal of halogen from organic compounds with H and it is usually advisable to have an alkali present to neutralize the halogen acid as it is formed. Many substances react even if merely suspended in aqueous alkalies. In halogen derivatives of ethylenic compounds the halogen may sometimes be removed without saturating the C:C linking or the halogen derivative of the saturated compound may be formed. Frequently the reaction proceeds smoothly to hydrogenation and removal of the halogen. With dihalogen compounds it is apparently impossible to obtain mono-derivatives As illustrations the following reductions are described: PhBr to C₆H₆, o-BrC₆H₄CO₂H, to BzOH, p-BrC₆H₄NO₂ to PhNH₂, chlorocaffeine to caffeine, chlorocrotonic to crotonic acid, o-ClC₆H₄CH:CHCO₂H to PhCH₂-CH₂CO₂H, (CHBrCO₂H)₂ to (CH₂CO₂H)₂. In the experiment, the researchers used many compounds, for example, (E)-4-Chlorobut-2-enoic acid (cas: 26340-58-9Synthetic Route of C4H5ClO2).

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 C4H5ClO2

And the article was included in ChemMedChem in 2011.Synthetic Route of C5H2Cl2O2S This article mentions the following:

A library composed of nitazoxanide-based analogs was synthesized and assayed for increased antibacterial efficacy against the pyruvate-ferredoxin oxidoreductase (PFOR) using microorganisms Helicobacter pylori, Campylobacter jejuni and Clostridium difficile. Derivatives were found to recapitulate and improve activity against these organism,s and select analogs were tested for their ability to disrupt the PFOR enzyme directly. The library was also screened for activity against staphylococci and resulted in the identification of analogs capable of inhibiting both staphylococci and all PFOR organisms at low micromolar min. inhibitory concentrations with low toxicity to human foreskin cells. In the experiment, the researchers used many compounds, for example, 2,5-Dichlorothiophene-3-carboxylic acid (cas: 36157-41-2Synthetic Route of C5H2Cl2O2S).
