In 2019,ACS Sustainable Chemistry & Engineering included an article by Wu, Chao; Xiao, Hai-Jing; Wang, Shu-Wen; Tang, Man-Sheng; Tang, Zi-Long; Xia, Wen; Li, Wen-Feng; Cao, Zhong; He, Wei-Min. Formula: C5H6O2. The article was titled 《Natural Deep Eutectic Solvent-Catalyzed Selenocyanation of Activated Alkynes via an Intermolecular H-Bonding Activation Process》. The information in the text is summarized as follows:
By employing cheap and biodegradable natural deep eutectic solvent as the catalyst and reaction media, the selective selenocyanation of activated alkynes via an intermol. H-bonding activation pathway has been achieved, which allows for the efficient construction of various Z-vinyl selenolates. In the experiment, the researchers used many compounds, for example, Ethyl propiolate(cas: 623-47-2Formula: C5H6O2)
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.Formula: C5H6O2
