摘要
在80~85℃,TEBA/H2O体系中,芳亚磺酸钠和2-(2-噻吩基)乙酮反应生成2-(4-R-苯磺酰基)-1-(2-噻吩基)乙酮,产率75~96%,操作简便,反应速度快。它们的结构均被IR、1HNMR元素分析所表证。
In the system of TEBA/H20 at 80-85℃, a series of 2-(4-R-phenylsulfonyl)-1-(2-thienyl) thanone (R=H, CH3, F, Cl, Br) were obtained in a yield of 75-96%, by the reaction of Arylsulfinate and 2-(2-thienyl)ethanone. The method is simple and the speed is fast.Their structures are confirmed by elemental analysis, IR and 1HNMR.
