(Salen)manganese(III)-catalyzed oxidation of silyl ethers with iodosylbenzene gave the corresponding carbonyl compounds. The enantioselective oxidation of symmetrical 1,3- and 1,4-disilyl ethers gave the corresponding optically active b- and g-siloxyketones, respectively (up to 93% ee).
在(Salen)manganese(III)催化下,用
碘酰苯氧化
硅醚,得到相应的羰基化合物。对称的1,3-和1,4-二
硅醚的选择性氧化分别得到相应的光学活性β-和γ-
硅氧基酮(最高可达93%的ee值)。
