It is also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. Application In Synthesis of 4595-59-9.
Nwachukwu, Chideraa I.;Patton, Leanna J.;Bowling, Nathan P.;Bosch, Eric research published 《 Ditopic halogen bonding with bipyrimidines and activated pyrimidines》, the research content is summarized as follows. The potential of pyrimidines to serve as ditopic halogen-bond acceptors is explored. The halogen-bonded cocrystals formed from solutions of either 5,5′-bipyrimidine (C8H6N4) or 1,2-bis(pyrimidin-5-yl)ethyne (C10H6N4) and 2 molar equivalents of 1,3-diiodotetrafluorobenzene (C6F4I2) have a 1:1 composition Each pyrimidine moiety acts as a single halogen-bond acceptor and the bipyrimidines act as ditopic halogen-bond acceptors. In contrast, the activated pyrimidines 2- and 5-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine (C14H13N3) are ditopic halogen-bond acceptors, and 1:1 halogen-bonded cocrystals are formed from 1:1 mixtures of each of the activated pyrimidines and either 1,2- or 1,3-diiodotetrafluorobenzene. A 1:1 cocrystal was also formed between 2-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine and 1,4-diiodotetrafluorobenzene, while a 2:1 cocrystal was formed between 5-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine and 1,4-diiodotetrafluorobenzene.
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., Application In Synthesis of 4595-59-9
