method for the regioselective synthesis of propargyl ethers by the coupling of propargyl alcohols with a range of other alcohols is described. The method employs an air- and moisture-tolerant rhenium-oxo complex ((dppm)ReOCl3) as a catalyst for the formation of sp3-carbon-oxygen bonds without the need for prior activation of the propargyl alcohol or deprotonation of the alcohol nucleophile. A broad range

A new method for the synthesis of propargylic ethers by FeCl3-catalyzed alcoholysis of propargylic acetates was developed. The reaction was carried out at room temperature in acetonitrile without exclusion of moisture or air. High product yields were obtained with excellent reaction regioselectivity.
