Xu, Chanchan;Li, Yuzhe;Lv, Le;Lin, Fang;Lin, Feng;Zhang, Zhijuan;Luo, Chaoyun;Luo, Dawei;Liu, Wei research published 《 Synthesis, characterization, luminescence properties of copper(I) bromide based coordination compounds》, the research content is summarized as follows. Two new copper bromide based coordination compounds 0D-Cu2Br2(3,5-dimethyl-pyridine)4 (1) and 1D-Cu2Br2(5-bromo-pyrimidine)2 (2) were synthesized and structurally characterized. X-ray diffraction analyses reveal that the inorganic module of both compounds is Cu2Br2 rhomboid dimer coordinated by the organic ligands. Compound 1 is a zero-dimensional (0D) mol. complex while compound 2 is one-dimensional (1D) extended structure. Photoluminescence measurement results show that 1 emits green photoluminescence peaked at 520 nm, with an IQY of 82.4%. Compound 2 emits red photoluminescence peaked at 630 nm, with an IQY of 2.1%. Both compounds exhibit potential as rare-earth metal free lighting phosphor alternatives.
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
