The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 4595-59-9, formula is C4H3BrN2, Name is 5-Bromopyrimidine. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Synthetic Route of 4595-59-9.
Liu, Yi;Zhou, Cuihan;Jiang, Meijing;Arndtsen, Bruce A. research published 《 Versatile Palladium-Catalyzed Approach to Acyl Fluorides and Carbonylations by Combining Visible Light- and Ligand-Driven Operations》, the research content is summarized as follows. The development of a general palladium-catalyzed carbonylative method to synthesize acyl fluorides RC(O)F (R = n-Bu, cyclohexyl, 4-methylphenyl, pyridin-3-yl, etc.) from aryl, heteroaryl, alkyl, and functionalized organic halides RX was described. Mechanistic anal. suggests that the reaction proceeds via the unique, synergistic combination of visible light photoexcitation of Pd(0) to induce oxidative addition with a ligand-favored reductive elimination. These together create a unidirectional catalytic cycle that is uninhibited by the classical effect of carbon monoxide coordination. Coupling the catalytic formation of acyl fluorides with their subsequent nucleophilic reactions has opened a method to perform carbonylation reactions with unprecedented breadth, including the assembly of highly functionalized carbonyl-containing products.
Synthetic Route of 4595-59-9, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., 4595-59-9.
