And the article was included in Chemistry – A European Journal in 2016.Name: 2-Ethynylpyrimidine This article mentions the following:
To shed light on intramol. charge-transfer phenomena in 1,2,3-triazole-linked materials, a series of 1,2,3-triazole-linked push-pull chromophores were prepared and studied exptl. and computationally. Investigated modifications include variation of donor and/or acceptor strength and linker moiety as well as regioisomers. Photophys. characterization of intramol. charge-transfer features revealed ambipolar behavior of the triazole linker, depending on the substitution position. Furthermore, non-centrosym. materials were subjected to second-harmonic generation measurements, which revealed the high nonlinear optical activity of this class of materials. In the experiment, the researchers used many compounds, for example, 2-Ethynylpyrimidine (cas: 37972-24-0Name: 2-Ethynylpyrimidine).
2-Ethynylpyrimidine (cas: 37972-24-0) belongs to pyrimidine derivatives. Pyrimidines are isomeric with two other forms of diazines: pyridazine, with the nitrogen atoms in the 1 and 2 positions; and pyrazine, with the nitrogen atoms in the 1 and 4 positions. A Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones enables an efficient and facile synthesis of structurally important pyrimidines via a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization.Name: 2-Ethynylpyrimidine
