SuperoxoCo(III) complexes, [Co(CN)5O2][X]3 where X = Et3N+ and (Ph3P)2N+, mediate the dioxygen incorporation into 2,6-di--butylphenols () with the same regioselectivity as that in the base-catalyzed oxygenation of . The superoxo species acts as a base but is not incorporated into the substrate.
Superoxo Co(III)配合物[Co(CN)5 O 2 ] [X] 3(其中X = Et 3 N +和(Ph 3 P)2 N +)介导将双氧引入到2,6-二-丁基苯酚中()具有与碱催化的氧合相同的区域选择性。超氧物质起碱的作用,但不掺入底物中。
