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. Electric Literature of 4595-59-9.
Das, Saikat;Murugesan, Kathiravan;Villegas Rodriguez, Gonzalo J.;Kaur, Jaspreet;Barham, Joshua P.;Savateev, Aleksandr;Antonietti, Markus;Koenig, Burkhard research published 《 Photocatalytic (Het)arylation of C(sp3)-H Bonds with Carbon Nitride》, the research content is summarized as follows. Mesoporous graphitic carbon nitride(mpg-CN)as a heterogeneous organic semiconductor photocatalyst for direct arylation of sp3 C-H bonds in combination with nickel catalysis are reported. This protocol has a broad synthetic scope (>70 examples including late-stage functionalization of drugs and agrochems.), was operationally simple, and shows high chemo- and regioselectivities. Facile separation and recycling of the mpg-CN catalyst in combination with its low preparation cost, innate photochem. stability, and low toxicity are beneficial features overcoming typical shortcomings of homogeneous photocatalysis. Detailed mechanistic investigations and kinetic studies indicate that an unprecedented energy-transfer process (EnT) from the organic semiconductor to the nickel complex was operated.
Electric Literature 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.
