      Thermo Scientific - Alfa Aesar

      Ethoxyacetylene is used in Arens-van Dorp synthesis to prepare propargyl alcohol via reaction with ketone. In organic synthesis, it undergoes [2+2] cycloaddition reactions with ketenes to give cyclobutenone derivatives. It is also used to prepare alpha, beta-unsaturated esters from ketones by following Meyer-Schuster rearrangement.Used with N-vinylamides and triflic anhydride in a direct, three-component synthesis of pyridines. Also used to prepare α, β-unsaturated esters from ketones via a Meyer-Schuster rearrangement.

      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.
