Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has the nitrogen atoms at positions 1 and 3 in the ring. 4595-59-9, formula is C4H3BrN2, Name is 5-Bromopyrimidine. The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides cytosine, thymine and uracil, thiamine (vitamin B1) and alloxan. Application In Synthesis of 4595-59-9.
Yu. Baranov, Andrey;Ryadun, Alexey A.;Sukhikh, Taisiya S.;Artem’ev, Alexander V. research published 《 Luminescent Cu(I) and Au(I) complexes based on diphenyl(5-pyrimidyl)phosphine》, the research content is summarized as follows. Diphenyl(5-pyrimidyl)phosphine (L) has been synthesized and its coordination abilities toward Cu(I) and Au(I) have been surveyed. The reaction of L with Cu(MeCN)4BF4 or CuI produces 1D polymers [Cu(L)(MeCN)2]BF4 and [Cu2I2(L)2], or 2D grids [Cu2I2(L)2], wherein P,N-bridging pattern of the ligand always appears. Treatment of L with 1 or 3 equivalent of Au(tht)Cl affords linear [Au(L)Cl] or trigonal pyramidal [Au(L)3Cl] complexes, in which the ligand is P-coordinated to Au(I). At 300 K, 1D polymers [Cu(L)(MeCN)2]BF4 and [Cu2I2(L)2] exhibit weak yellow and moderate green emission, resp., which strongly enhances upon colling to 77 K. Complex [Au(L)3Cl] at 300 K emits strong sky-blue phosphorescence (λem = 492 nm) with the quantum yield of 50%.
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
