Using microwave irradiation and protic ionic liquids (pIL) as co-solvent and catalyst for the synthesis of several diphenylmethyl ethers was achieved. The desired ethers were isolated simply by filtration through a silica plug to remove the pIL and proceeded in high yields (60–98%). These reactions were extremely rapid (10–30 min) and occurred under mild conditions (80 °C). This protocol was also successfully
使用微波辐射和质子离子液体(pIL)作为助溶剂和催化剂,合成了几种二苯甲基醚。只需通过硅胶塞过滤除去所需的pIL,即可分离出所需的醚,并以高收率(60-98%)进行。这些反应非常迅速(10–30分钟),并且在温和的条件下(80°C)发生。该方案也成功地应用于硫醚的合成。
