Descripción

Ethyl 2-butynoate is used as a precursor for the synthesis of 3-ethyl, 1-methyl 1-(2-nitrophenyl)-cyclopent-3-ene-1,3-dicarboxylate, alkenylsilanols and tricyclic aziridine derivatives. It acts as a methanogenesis inhibitor. As an electron deficient alkyne derivative, it plays a vital role in the preparation of 1,3-dienes catalyzed by rhodium(I)/H8-BINAP complex.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El 2-butinoato de etilo se utiliza como precursor para la síntesis de 3-etil, 1-metil 1-(2-nitrofenil)-ciclopent-3-eno-1,3-dicarboxilato, alquenilsilanoles y derivados de la aziridina tricíclicos. Actúa como inhibidor de la metanogénesis. Como derivado de alquinos con deficiencia de electrones, desempeña un papel vital en la preparación de 1,3-dienos catalizados por el complejo rodio(I)/H8-BINAP.
