Dioxiranes: a half-century journey

“…In 1953 Doering and Dorfman proposed a different reaction path for the BVO that did not involve a dioxirane intermediate 22 but a Criegee intermediate, which was supported by 18 O-enriched mass-spectrometric studies. [22][23][24][25][26] The Criegee intermediate is a carbonyl oxide having zwitterionic attributes. [27][28][29] In 1972, Talbott and Thompson reported the first synthesis of the cyclic peroxides 4a-c, which can be shown as diradical 5 or zwitterionic 6-7, respectively (Scheme 2).…”
