| Hazard Information | Back Directory | [Chemical Properties]
Clear orange to brown solution | [Uses]
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. | [Uses]
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. | [Preparation]
Ethoxyethyne can be prepared from chloroacetaldehyde diethyl acetal (70%). | [Hazard]
Ethoxyethyne is moisture sensitive; potential fire hazard with certain metal salts. Use in a fume hood. |
