Arens–van Dorp Synthesis

Name:
Arens–van Dorp Synthesis
Detailed information:
The preparation of alkoxyethynyl alcohols from ketones and ethoxyacetylene. In the Isler modification, β-chlorovinyl ether is reacted with lithium amide to give lithium ethoxyacetylene which is then condensed with the ketone. This avoids the tedious preparation of ethoxyacetylene.
