An efficient procedure for the synthesis of phenacyl and benzyl azolium salts in 2,2,2-trifluoroethanol and 1,1,1,3,3,3-hexafluoroisopropanol as fluorous alcohols have been developed. This synthetic methodology has some advantages with the respect to yield, atom efficiency, solvent and reagents used and wastes generated when compared to the currently in use methods. Using this procedure, a range of phenacyl and benzyl azolium salts can be synthesized with good to excellent yields. The pure salts are separated from the reaction mixture by simple filtration and washing with dry ether.
一种高效的合成苯乙酰和苄基唑啉盐的方法已在2,2,2-三氟乙醇和1,1,1,3,3,3-六氟异丙醇等氟醇中开发。与目前使用的方法相比,该合成方法在产率、原子效率、所用溶剂和试剂以及产生的废物方面具有一些优势。使用该程序可以合成一系列苯乙酰和苄基唑啉盐,产率良好至优异。纯盐通过简单过滤和干醚洗涤从反应混合物中分离出来。
