The FeCl2/K2CO3 catalyst system was developed successfully for the N-alkylation of sulfonamides with benzylic alcohols via borrowing hydrogen method. XPS analysis suggested a possible catalyst cycle between Fe(II) and Fe(0). Under the optimized condition, the scope of the protocol was demonstrated in 21 different alkylation reactions. High yields, in general >90%, are achieved in most cases.
成功开发了FeCl 2 / K 2 CO 3催化剂体系,用于借借氢法将磺酰胺与
苄醇进行N-烷基化反应。XPS分析表明,Fe(II)和Fe(0)之间可能存在催化剂循环。在优化的条件下,该方案的范围在21种不同的烷基化反应中得到了证明。在大多数情况下,通常都可以达到90%以上的高收率。
