A photo-semipinacol rearrangement of unactivated allylic alcohols is reported. Aliphatic as well as aromatic groups participate as migrating groups, yielding a variety of α,α-disubstituted ketones. The operationally simple conditions prescribe 1 mol % benzothiazinoquinoxaline as organophotocatalyst, 0.5 mol % Co-salen, and 10 mol % lutidinium triflate and, importantly, display reactivity complementary
据报道,未活化的烯丙醇发生光-半频那醇重排。脂肪族和芳香族基团作为迁移基团参与,产生各种 α,α-二取代酮。操作简单的条件规定 1 mol% 苯并噻嗪喹喔啉作为有机光催化剂、0.5 mol% Co-salen 和 10 mol% 三氟甲磺酸钚,重要的是,显示出与使用布朗斯台德酸的程序互补的反应性。
