摘要
噻吩用过溴吡啶氢酸盐在四氯化碳和48%氢溴酸中进行选择性溴化,可得到98%的2溴噻吩.该反应时间短,收率高,选择性好,操作方便,是噻吩单溴化又一新方法.
The reaction of thiophene with pyridine hydrobromide perbromide(C 5H 5NHB r·Br 2) in 48% hydlrobromic acid and tetrachloromethane gives 2bromothiophene in 90% yield. That reaction character is of short reaction period time. high selectivity and moderate reaction condition.
