The synthesis of 30 heterocyclic 1,3-dicarbonyl compounds, the corresponding hydroperoxides and the 10 alcohols, their characterization, and the limitations of the procedure are described. In addition, the mechanism of the hydroperoxidation and the redox decomposition of the hydroperoxides are discussed. http://www.mdpi.com/1420-3049/16/11/9562 Molecular Diversity Preservation International 2011-11 eng journal article VoR http://hdl.handle.net/2298/25261 https://kumadai.repo.nii.ac.jp/records/26605 22089863 10.3390/molecules16119562 14203049 Molecules 16 11 9562 9581 https://kumadai.repo.nii.ac.jp/record/26605/files/Molecules-,2011,16,9562-9581-full version.pdf application/pdf 708.4 kB 2020-03-02
