And the article was included in Phosphorus, Sulfur and Silicon and the Related Elements in 2020.Product Details of 20776-54-9 This article mentions the following:

A series of novel 1,2,3-benzotriazin-4-one derivatives containing 4,5-dihydrothiazole-2-thiol I (R = H, 5-OMe, 7-F, 8-NO₂, etc.) was synthesized. The bioassay results showed that compounds I (R = 7-OMe, 6-NO₂, 7-Cl (A)) exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita at the concentration of 10.0 mg L^-1 in vivo. Compound (A) showed excellent nematicidal activity with inhibition 68.3% at a concentration of 1.0 mg L^-1. It suggested that the structure of 1,2,3-benzotriazin-4-one containing 4,5-dihydro-thiazole-2-thiol could be optimized further. In the experiment, the researchers used many compounds, for example, 2-Amino-4-iodobenzoic acid (cas: 20776-54-9Product Details of 20776-54-9).

2-Amino-4-iodobenzoic acid (cas: 20776-54-9) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Product Details of 20776-54-9

Azine and Diazine Functionalization Using 2,2,6,6-Tetramethylpiperidino-Based Lithium-Metal Combinations: Application to the Synthesis of 5,9-Disubstituted Pyrido[3′,2′:4,5]pyrrolo[1,2-c]pyrimidines was written by Marquise, Nada;Nguyen, Tan Tai;Chevallier, Floris;Picot, Laurent;Thiery, Valerie;Lozach, Olivier;Bach, Stephane;Ruchaud, Sandrine;Mongin, Florence. And the article was included in Synlett in 2015.COA of Formula: C4H2ClIN2 This article mentions the following:

The synthesis of triaryl methanols was investigated by reacting different 4-metalated 2-substituted pyrimidines with diaryl ketones, the latter being generated by deprotocupration-aroylation of azine and diazine substrates. Cyclization of the triaryl methanols thus obtained afforded pyrido[3′,2′:4,5]pyrrolo[1,2-c]pyrimidines, which were evaluated for kinase inhibition and antiproliferative activities in melanoma cells. In the experiment, the researchers used many compounds, for example, 2-Chloro-4-iodopyrimidine (cas: 395082-55-0COA of Formula: C4H2ClIN2).

2-Chloro-4-iodopyrimidine (cas: 395082-55-0) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.COA of Formula: C4H2ClIN2

Two-Directional Approach for the Rapid Synthesis of 2,4-Bis-Aminoaryl Pyridine Derivatives was written by Morgentin, Remy;Barlaam, Bernard;Foote, Kevin;Hassall, Lorraine;Hawkins, Janet;Jones, Clifford D.;Le Griffon, Antoine;Peru, Aurelien;Ple, Patrick. And the article was included in Synthetic Communications in 2012.Category: iodides-buliding-blocks This article mentions the following:

We have developed two different approaches in parallel to rapidly access 2,4-bis(aminoaryl)pyridine compounds, e.g., I, from a common starting material. The C-4/C-2 approach uses palladium-mediated coupling reactions to sequentially functionalize C-4 and then C-2. An alternative C-2/C-4 route uses a regioselective SNAr reaction to first substitute at C-2 then subsequently at C-4 by a palladium-mediated reaction. Both approaches have been used successfully to provide a range of 2,4-bis(aminoaryl)pyridine compounds In the experiment, the researchers used many compounds, for example, 2-Chloro-5-(trifluoromethyl)-4-iodopyridine (cas: 505084-55-9Category: iodides-buliding-blocks).

2-Chloro-5-(trifluoromethyl)-4-iodopyridine (cas: 505084-55-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Category: iodides-buliding-blocks

A silver-promoted oxidative benzylic C-H trifluoromethoxylation has been reported for the first time. With trifluoromethyl arylsulfonate as the trifluoromethoxylation reagent, various arenes, having diverse functional groups, undergo trifluoromethoxylation of their benzylic C-H bonds to form trifluoromethyl ethers under mild reaction conditions. In addition, the trifluoromethoxylation and the fluorination of Me groups of electron-rich arenes have been achieved to prepare α-fluorobenzyl trifluoromethyl ethers in one step.

Palladium-Catalyzed Carbonylative Couplings of Vinylogous Enolates: Application to Statin Structures was written by Makarov, Ilya S.;Kuwahara, Takashi;Jusseau, Xavier;Ryu, Ilhyong;Lindhardt, Anders T.;Skrydstrup, Troels. And the article was included in Journal of the American Chemical Society in 2015.SDS of cas: 34091-51-5 This article mentions the following:

The first Pd-catalyzed carbonylative couplings of aryl and vinyl halides with vinylogous enolates are reported to generate products derived from C-C bond formation exclusively at the γ-position. Good results were obtained with a dienolate derivative of acetoacetate (1,3-dioxin-4-one). E.g., in presence of Pd(dba)₂, Xantphos, and LiHMDS in THF in a two-chamber reactor system using SilaCOgen as the carbon monoxide source, carbonylative coupling of 4-NCC₆H₄I with 2,2,6-trimethyl-4H-1,3-dioxin-4-one gave 77% I. These transformations occurred at room temperature and, importantly, with only stoichiometric carbon monoxide in a two-chamber reactor. The methodol. was applied to the synthesis of two members of the statin family generating the cis-3,5-diol acid motif by a γ-selective carbonylation followed by a cis-stereoselective reduction of the 3,5-dicarbonyl acid intermediates. In the experiment, the researchers used many compounds, for example, 5-Iodo-1-methyl-1H-pyrazole (cas: 34091-51-5SDS of cas: 34091-51-5).

5-Iodo-1-methyl-1H-pyrazole (cas: 34091-51-5) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.SDS of cas: 34091-51-5
