- Formal Cycloaddition of Molecular Oxygen, 1,3-Diketone, and Olefin. Synthesis and Reactions of Cyclic Peroxides
-
Formal cycloaddition of molecular oxygen, 1,3-diketones, and olefins took place by electrochemical oxidation.A catalytic amount of electricity was sufficient for the reaction, and an electroinitiated radical chain mechanism was proposed.The reaction was also initiated by a radical initiator.The resulting cyclic peroxides reacted with acids and some reducing agents such as ferrous sulfate, thiurea, and copper(I) chloride to give oxygen-oxygen bond cleavage products.

- Oxidative Cycloaddition of 1,3-Diketone and Olefin Using Electroorganic Chemistry
-
The electrochemical oxidation of 1,3-diketones and 2-substituted 1,3-diketones in the presence of olefin gave the cycloadducts, dihydrofuran and tetrahydrofuran derivatives, respectively.A mechanism involving electrooxidative formation of the radical intermediate from the diketone followed by addition to the olefin has been proposed.

- OXIDATIVE CYCLOADDITION OF 1,3-DIKETONE AND OLEFIN USING ELECTROORGANIC CHEMISTRY
-
Electrochemical oxidation of 1,3-diketones in the presence of olefins afforded the formal cycloaddition products, dihydrofuran derivatives or tetrahydrofuran derivatives.A mechanism involving attack of a radical intermediate to an olefin has been proposed.
