The oxidation of organosilanes to silanols constitutes an attractive transformation for both industry and academia. Bypassing the need for stoichiometric oxidants or precious metal catalytic complexes, the first organocatalytic oxidation of silanes has been accomplished. Catalytic amounts of 2,2,2-trifluoroacetophenone, in combination with the green oxidant H2O2, lead to excellent to quantitative yields
有机硅烷氧化为硅烷醇构成了工业界和学术界的诱人转变。绕过对化学计量的氧化剂或贵金属催化络合物的需求,已经完成了硅烷的第一有机催化氧化。催化量的2,2,2-三氟苯乙酮与绿色氧化剂H 2 O 2结合,可在较短的反应时间内达到极佳的定量收率。可以容许各种烷基,芳基,烯基和炔基取代基,从而为高度希望的转化提供了一种简单,廉价,有效和实用的解决方案。
