The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 1722-12-9, formula is C4H3ClN2, Name is 2-Chloropyrimidine. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Recommanded Product: 2-Chloropyrimidine.
Das, Dharmendra;Bhosle, Akhil A.;Panjikar, Padmini C.;Chatterjee, Amrita;Banerjee, Mainak research published 《 Mn(I)-Catalyzed Mechanochemical C-H Bond Activation: C-2 Selective Alkenylation of Indoles》, the research content is summarized as follows. An efficient mechanochem. method for manganese-catalyzed regioselective C-H bond alkenylation of indoles with alkynes is developed. The present method allows direct C-2 alkenylation of indoles in a mixer mill, employing a com. available low-valent manganese catalyst, MnBr(CO)5, providing a sustainable route to hydroindolation on alkynes. The developed protocol is highly C-2-selective by the presence of a heteroaromatic N atom as a directing group (namely, pyridyl) and tolerant of structural variations with electron-rich and electron-deficient substituents both in the indoles and in the alkynes. Silica as the grinding media and the presence of a catalytic amount of acid and DIPEA as the base worked favorably to afford a variety of 2-alkenyl indoles in excellent yields at ambient conditions. The terminal alkynes offered better results than internal alkynes in terms of yields and reactivity. The scalability of the reaction was demonstrated by conducting the reactions in the gram scale. A short study indicated that a little tweak in conditions can be useful for double alkenylation to afford carbazole derivatives in moderate yields. A low E-factor along with a clean reaction profile, an easy exptl. setup, the absence of an anhydrous condition, and being devoid of toxic organic solvents proclaims its advantage over the available conventional methods.
Recommanded Product: 2-Chloropyrimidine, 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.
