Catalyst-free Straightforward Synthesis of Propargylic Ethers from their Carbonates and Alcohols under Microwaves Irradiation

Background: Propargylic derivatives are important reagents and building blocks in organic synthesis. They can be obtained starting with propargylic alcohols or their protected forms. The actual methods rely on the use of acidic or metal-catalyzed approachs. These efficient methods however need to use solvents and metals, that are sometimes toxic or expensive. Ways to prepare those derivatives without metals or solvents can thus be an interesting alternative. Keywords: Alcohols, catalyst-free, microwaves, propargylic carbonate, propargylic ethers, solvent-free.
