Ethyl 2-Butynoate (Cas 4341-76-8)

Ethyl 2-butynoate cas:4341-76-8, also known as ethyl tetrolate, is an electron-deficient alkyne ester with a molecular weight of 112.13 g/mol . Key applications include: Precursor in synthesizing tricyclic aziridines, alkenylsilanols, and cyclopentene dicarboxylates . Methanogenesis inhibitor and key reagent in Rh(I)/H8-BINAP-catalyzed 1,3-diene preparations . Intermediate in stereoretentive cross-coupling reactions and total syntheses of natural products like waixenicin A . Ethyl 2-butynoate cas:4341-76-8, a 2-alkynoate is a methanogenesis inhibitor. It is an electron deficient internal alkyne that has been reported to undergo codimerization with alkenes to form 1,3-dienes catalyzed by rhodium(I)/H8-BINAP complex.
