A Solvent-free Procedure for Synthesis of N-Sulfonylimines Catalyzed by Zr(SO4)2·4H2O/SiO2 Solid Acid under Microwave Irradiation
【摘要】 微波辐射无溶剂条件下,以Zr(SO4)2?4H2O/SiO2固体酸为催化剂,芳香醛与芳香磺酰胺反应合成了一系列芳香磺酰亚胺化合物.此方法具有操作简便,催化剂价廉易得、活性高、可回收重复使用、对环境友好等优点.
【Abstract】 A manipulative simple and rapid procedure for the synthesis of N-sulfonylimines from aldehydes with sulfonamides was described. The reaction was conducted under microwave irradiation conditions in the absence of solvent using Zr(SO4)2?4H2O/SiO2 solid acid as catalyst . This solid acid is cheap, highly-active, chemically green and reusable.
