Recommanded Product: Ethyl propiolate And the article was included in Polymer Chemistry in 2020. The article conveys some information:
We herein report a facile and efficient multicomponent polymerization approach to construct fused heterocyclic polymers with imidazo[2,1-b]thiazole units in the main chain. A preliminary polymerization reaction was carried out as a model reaction with 1,4-phthalaldehyde, [6,6′-bibenzothiazole]-2,2′-diamine and 1-ethynyl-4-hexylbenzene as monomers, and different polymerization conditions, including the catalyst, catalyst amount and solvent, were optimized. Based on the optimized conditions, a series of fused heterocyclic conjugated polymers containing imidazo[2,1-b]thiazole units with high-mol. weights (Mn up to 5.7 x 104) in moderate yields (up to 54.3%) were obtained. With imidazo[2,1-b]thiazoles embedded in the main chains, the resulting polymers possess outstanding solubility, relatively good thermal stability and low energy bands. A possible mechanism was proposed for the polymerization including a 5-exo-dig cyclization and then an aromatization process. In the part of experimental materials, we found many familiar compounds, such as Ethyl propiolate(cas: 623-47-2Recommanded Product: Ethyl propiolate)
Ethyl propiolate(cas: 623-47-2) is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.Recommanded Product: Ethyl propiolate
