Solvent free synthesis of 1-alkoxyphosphonium chlorides for stereoselective multipurpose vinyl ethers CheemaZain Maqsood GondalHumaira Yasmeen SiddiquiHina ChoudharyMuhammad Iqbal 2019 <p>An efficient solvent free method is developed for the preparation of structurally diverse 1-alkoxymethylphosphonium chlorides in high yield. One of the prepared salts derived from (1 <i>R</i>,2<i>S</i>,5<i>R</i>)-(−)-Menthol auxiliary was further employed for the synthesis of vinyl ethers, where up to 99% stereoselectivity was achieved.</p>
