2-Cyanothiazole (cas: 1452-16-0) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone. Various laboratory methods exist for the organic synthesis of thiazoles. Prominent is the Hantzsch thiazole synthesis is a reaction between haloketones and thioamides.Reference of 1452-16-0

Diketopyrrolopyrrole based small molecular semiconductors containing thiazole units for solution-processed n-channel thin-film transistors was written by Tang, Meizhu;Wu, Sicheng;Xing, Weilong;Shen, Hongguang;Xiang, Lanyi;Liang, Yingying;Xu, Wei;Zhu, Daoben. And the article was included in Dyes and Pigments in 2019.Reference of 1452-16-0 This article mentions the following:

In this work, three diketopyrrolopyrrole-based conjugated small mol. semiconductors characterized by the combination of a diketopyrrolopyrrole (DPP) central core, thiazole π-conjugated moiety, and dicyanovinyl end group with different alkyl side chain substituents, 2TzDPPA1-2DCV, 2TzDPPA2-2DCV, and 2TzDPPA3-2DCV were synthesized. These small mols. have a similar narrow band gap of about 1.50 eV and deep LUMO energy level at -4.30 eV. Under ambient conditions, electron mobilities of 0.28 cm2 V-1 s-1, 0.13 cm2 V-1 s-1, 0.25 cm2 V-1 s-1 for solution processed thin films of 2TzDPPA1-2DCV, 2TzDPPA2-2DCV, and 2TzDPPA3-2DCV were obtained, due to high crystallinity and well-organized mol. stacking. Compared with the other two materials, thin films of 2TzDPPA1-2DCV enable the best OFET performance with desirable Ion/Ioff rates exceeding of 107, attribute to the coefficient of smoother film morphol. and stronger crystallinity. These results reveal that introducing the thiazole unit into the DPP-based conjugated skeleton is conducive to enhance the crystallinity and tailor LUMO energy levels which ensure good performance and excellent stability of these mols. as active materials for n-channel electronic devices. In the experiment, the researchers used many compounds, for example, 2-Cyanothiazole (cas: 1452-16-0Reference of 1452-16-0).

2-Cyanothiazole (cas: 1452-16-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at 未 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 掳C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Name: 2-Cyanothiazole

Schmidt reaction in ionic liquids: highly efficient and selective conversion of aromatic and heteroaromatic aldehydes to nitriles with [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent was written by Nandi, Ganesh C.;Laali, Kenneth K.. And the article was included in Tetrahedron Letters in 2013.Name: 2-Cyanothiazole This article mentions the following:

A mild and selective method is presented for the conversion of aromatic and heteroaromatic aldehydes to nitriles via the Schmidt reaction with TMSN3 by using [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent. E.g., in the presence of this catalyst in [BMIM][PF6], reaction of 2-MeOC6H4CHO with TMSN3 gave 100% 2-MeOC6H4CN. The method offers high yields and simple product isolation, and avoids the use of liquid superacids or corrosive Lewis acids commonly employed for this transformation. It also offers some potential for recycling/reuse of the IL solvent. In the experiment, the researchers used many compounds, for example, 2-Cyanothiazole (cas: 1452-16-0Name: 2-Cyanothiazole).
