as a convenient one-flask transformation with consecutive addition of the appropriate reagents. Exchange of solvents or removal of byproducts prior to isolation of the product is not required. The arene diazonium salts are isolated from the reaction mixture by simple filtration. Two complementary protocols are presented, and the utility of the reaction is exemplified for a synthesis of the diarylheptanoid
芳族乙酰胺四氟硼酸酯可以由芳族乙酰胺经一系列的脱乙酰基,重氮化和沉淀(由阴离子交换诱导)合成。该反应以方便的一瓶转化进行,并连续添加适当的试剂。不需要在分离产物之前交换溶剂或除去副产物。通过简单的过滤从反应混合物中分离出芳烃重氮盐。提出了两种互补的方案,并举例说明了该反应用于合成二芳基庚烷天然产物去-O-甲基中心洛宾的方法。
