ETHYL 2-BUTYNOATE 98% (C005B-039975)

General description

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.

Application

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
