Reference of Ethyl propiolateIn 2019 ,《Triple copper catalysis for the synthesis of vinyl triazoles》 appeared in Green Chemistry. The author of the article were Baldassari, Lucas L.; Cechinatto, Eduardo A.; Moro, Angelica V.. The article conveys some information:
Synthesis of vinyl 1,2,3-triazoles through a one-pot sequence, enabled by the same copper catalyst of three different reactions: hydroboration involving an alkyne, azidation for a vinyl boronate and azide-alkyne cycloaddition was reported. In the part of experimental materials, we found many familiar compounds, such as Ethyl propiolate(cas: 623-47-2Reference of 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.Reference of Ethyl propiolate
