Cosensitized Electron-Transfer Photooxygenation
Abstract
The research projects during this period were focused on oxidation chemistry involving electron-transfer processes and molecular oxygen. Major accomplishments of our investigations include the following: (1) The stereochemical course of the DCA-sensitized electron-transfer photooxygenation of cis- and trans-2,3-bis(4-methoxyphenyl) oxirane has been elucidated. The reaction proceeds by a chain reaction to yield exclusively the cis ozonide. (2) Adamantyl-substituted alkenes were found to undergo oxygenation via non-photochemical process to form stable, 1,2-dioxetanes. (3) A mechanic study of the S-oxygenation of substituted thioanisoles by horseradish peroxidase and choloroperoxidase has shown that both electron exchange and direct oxygen-atom transfer are involved in these reactions.
