Ethyl 2-butynoate, 1 X 1 g (425117-1G)

Ethyl 2-butynoate, 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. The annulation of thioamides with ethyl 2-butynoate catalyzed by tri-n-butylphosphine to form thiazolines has been investigated. Ethyl 2-butynoate was used in the study of its effect on in vitro degradation and microbial biomass production. It may be used in the synthesis of the following: •3-ethyl, 1-methyl 1-(2-nitrophenyl)-cyclopent-3-ene-1,3-dicarboxylate •tricyclic aziridine derivatives •alkenylsilanols
