A new O‐benzylating reagent, that is, 4‐(4,6‐diphenoxy‐1,3,5‐triazin‐2‐yl)‐4‐benzylmorpholinium trifluoromethanesulfonate (DPT‐BM), has been developed. Benzyl cation equivalents are generated from DPT‐BM by dissolving the compound in a solvent at room temperature under non‐acidic conditions. The benzylation of various alcohols by using a combination of DPT‐BM and magnesium oxide provided the benzyl
已开发出一种新的O-苄基化试剂,即4-(4,6-二苯氧基-1,3,5-三嗪-2-基)-4-苄基吗啉三氟甲磺酸盐(DPT-BM)。通过在室温下于非酸性条件下将化合物溶解在溶剂中,可以从DPT-BM中生成苄基阳离子当量。通过结合使用DPT-BM和氧化镁对各种醇进行苄基化处理,可以提供高收率的苄基醚。
