Herein we report the first catalytic transfer hydrogenation of silyl enol ethers. This metal free approach employs tris(pentafluorophenyl)borane and 2,2,6,6‐tetramethylpiperidine (TMP) as a commercially available FLP catalyst system and naturally occurring γ‐terpinene as a dihydrogen surrogate. A variety of silyl enol ethers undergo efficient hydrogenation, with the reduced products isolated in excellent
在此,我们报道了硅烯醇醚的首次催化转移氢化。这种无金属方法采用三(五氟苯基)硼烷和 2,2,6,6-四甲基哌啶(TMP)作为市售 FLP 催化剂系统,并使用天然存在的 γ-萜品烯作为二氢替代物。各种甲硅烷基烯醇醚进行有效的氢化,分离出的还原产物具有优异的产率(29 个实例,平均产率 82%)。
