[reaction; see text] The catalytic electrophilic activation of hydrogen peroxide with transition metal compounds toward reaction with nucleophiles is a matter of very significant research and practical interest. We have now found that use of perfluorinated alcoholic solvents such as 1,1, 1,3,3,3-hexafluoro-2-propanol in the absence of catalysts allowed electrophilic activation of hydrogen peroxide toward epoxidation of alkenes and the Baeyer-Villiger oxidation of ketones.
[反应;见正文] 过渡金属化合物对过氧化氢进行催化亲电活化以使其与亲核试剂发生反应是一个具有重大研究和实际意义的课题。我们现已发现,在无催化剂的情况下使用全氟醇类溶剂,如1,1,1,3,3,3 - 六氟 - 2 - 丙醇,可使过氧化氢发生亲电活化,从而实现烯烃的环氧化和酮的拜耳 - 维利格氧化反应。
