Application of C4H3ClN2, 2-Chloropyrimidine is a monochlorinated pyrimidine with plant growth regulating activity. Chloropyrimidine is a useful reagent in the preparation of antivirals and other biologically active compounds.
2-Chloropyrimidine undergoes cobalt-catalyzed cross-coupling reaction with aryl halides.
2-Chloropyrimidine is a molecule that can be synthesized by the oxidation of pyrimidine with hydrogen peroxide and hydrochloric acid. The reaction proceeds through an electrochemical process in which the oxidation catalyst is a platinum electrode. This reaction is catalyzed by the nucleophilic attack of malonic acid on the chloropyrimidine at the methylene group. This efficient method for making 2-chloropyrimidine has been applied to synthesize aryl halides, including phenyl chloropyrimidine and pyridyl chloropyrimidine, from their corresponding chloride and bromide precursors. The fluorescence properties of 2-chloropyrimidine have been studied in coordination chemistry, where it forms complexes with metal ions such as Mn2+. In this study, it was found that adsorption mechanisms are dependent on molecular size, charge density, kinetic energy, and adsorbent surface area., 1722-12-9.

Slack, Eric D.;Colacot, Thomas J. research published 《 Understanding the Activation of Air-Stable Ir(COD)(Phen)Cl Precatalyst for C-H Borylation of Aromatics and Heteroaromatics》, the research content is summarized as follows. A newly developed robust catalyst [Ir(COD)(Phen)Cl] (A) was used for the C-H borylation of three dozen aromatics and heteroaromatics with excellent yield and selectivity. Activation of the catalyst was identified using catalytic amounts of H2O, alcs., etc., when B2pin2 was used in noncoordinating solvents, while for THF catalytic use of HBpin was required. The results were on par with the in situ based expensive system [Ir(OMe)(COD)]2/dtbbpy or Me4Phen.

Skrodzki, Maciej;Ortega Garrido, Victor;Csaky, Aurelio G.;Pawluc, Piotr research published 《 Searching for highly active cobalt catalysts bearing Schiff base ligands for Markovnikov-selective hydrosilylation of alkynes with tertiary silanes》, the research content is summarized as follows. The search for simple and easy-to-synthesize ligands for bench stable cobalt (pre)catalysts that would ensure high activity and selectivity in alkyne hydrosilylation reactions is an interesting current challenge. Herein, we report that a cobalt(II) complex bearing pyrimidine-imine-2H-imidazole ligand activated by LiHBEt3 exhibits not only high catalytic activity, but also unprecedented tolerance towards tertiary silanes in highly regioselective Markovnikov hydrosilylation of aliphatic and aromatic terminal alkynes to give α-vinylsilanes. In addition, a variety of 1-aryl-2-(trimethylsilyl)acetylenes have been hydrosilylated efficiently by diphenylsilane in the presence of [Co(L)Cl2]/LiHBEt3 catalytic system to yield (E)-1-aryl-1,2-bis(silyl)ethenes with high selectivity. Such selectivity is very rarely observed for cobalt-catalyzed hydrosilylation of silylacetylenes.

A general method for the N-arylation of sulfamides with aryl bromides is described. The protocol leverages a dual-catalytic system, with [Ir(ppy)2(dtbbpy)]PF6 as a photosensitizer, NiBr2•glyme as a precatalyst, and DBU as a base, and proceeds at room temperature under visible light irradiation Using these tactics, aryl boronic esters and aryl chlorides can be carried through the reaction untouched. The developed reactions efficiently engage simple bromoarenes and primary sulfamides in between 66% and quant. yields. For more challenging substrates, such as secondary sulfamides, reaction efficiency is documented.

Neglected tropical diseases remain among the most critical public health concerns in Africa and South America. The drug treatments for these diseases are limited, which invariably leads to fatal cases. Hence, there is an urgent need for new antitrypanosomal drugs. To address this issue, a large number of diverse heterocyclic compounds were prepared Straightforward synthetic approaches tolerated pre-functionalized structures, giving rise to a structurally diverse set of analogs. We report on a set of 57 heterocyclic compounds with selective activity potential against kinetoplastid parasites. In general, 29 and 19 compounds of the total set could be defined as active against Trypanosoma cruzi and T. brucei brucei, resp. (antitrypanosomal activities <10μM). The present work discusses the structure-activity relationships of new fused-ring scaffolds based on imidazopyridine/pyrimidine and furopyridine cores. This library of compounds shows significant potential for anti-trypanosomiases drug discovery.

Phosphonic acids and esters are pervasive throughout the discovery sciences, from medicine and agriculture, to materials and asym. synthesis. The ability to install and construct mol. architecture containing phosphonic functionality has led to the development of new medicines and catalyst systems in the field of organo- and organometallic catalysis. To continue the advancement in the field, improved synthetic access to phosphorous-containing motifs is required. In particular, heterocyclic phosphonates and their acid derivatives are so far underdeveloped. The method described herein provides a robust and operationally simple procedure for the installation of various phosphonates to a wide range of electrophilic heterocycles.

The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines. Pinner first proposed the name “pyrimidin” in 1885. 109-12-6, formula is C4H5N3, Name is Pyrimidin-2-amine. The parent compound was first prepared by Gabriel and Colman in 1900, by conversion of barbituric acid to 2,4,6-trichloropyrimidine followed by reduction using zinc dust in hot water. Formula: C4H5N3.

Shukla, Pratibha;Deswal, Deepa;Narula, Anudeep Kumar research published 《 Monomeric silica supported interaction of TOSMIC with highly functionalized imines: A green approach to azetidines via ABB -type cycloaddition reaction》, the research content is summarized as follows. The reaction of TOSMIC with highly functionalized imines R1CH=NR2 (R1 = Ph, Pr, 1-naphthyl, etc.; R2 = 2-pyridyl, pyrimidin-2-yl, pyrazin-2-yl, 1,3-thiazol-2-yl) has been reported. The use of monomeric silica as a catalyst for the reaction has been reported for the first time. The main product of the reported green methodol., formed by the sequential attack of the two TOSMIC units upon the carbon-nitrogen double bond of highly functionalized imines, has been identified as bis(tosylmethyl)azetidines I, a four member N-heterocyclic system. The scope of the reaction concerning functionalized imines and TOSMIC reactivity has been studied and determined, keeping in view the advantage of using TOSMIC as component B for the ABB-type cycloaddition reactions.
