The development of economical synthetic methods remains an important step toward the widespread use of conjugated polymers. Most well-established methods require either prefunctionalization with organometallic reagents or the use of expensive transition-metal catalysts. We have shown that 2-hydroxyalkyl- and 2-hydroxyaryl-substituted thiazole N-oxides can proceed through an ipso-arylative condensation that yields bithiazole-containing conjugated small mols. and polymers. The use of 2-hydroxyaryl substituents enables access to a wide scope of thiazole N-oxide substrates and presents an economical route to the synthesis of bithiazole-based conjugated polymers with varying phys. and electronic properties. In the experiment, the researchers used many compounds, for example, 5-Phenylthiazole (cas: 1826-13-7Category: thiazole).
5-Phenylthiazole (cas: 1826-13-7) 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 δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Various laboratory methods exist for the organic synthesis of thiazoles. Prominent is the Hantzsch thiazole synthesis is a reaction between haloketones and thioamides.Category: thiazole
