FORMATION OF 1,2-DIOXOLANE IN THE SINGLET OXYGENATION OF A SILICON-SILICON ?-BOND: PEROXONIUM ION INTERMEDIATE

Article abstract of DOI:10.1016/S0040-4039(00)70656-3

Singlet oxygenation of 1,1,2,2-tetramesityl-1,2-disilirane 1a afforded the corresponding cyclic peroxide 3a.Trapping experiments and theoretical studies of the initially formed peroxidic intermediate were also carried out.Peroxonium ion type intermediate is required to rationalize the results.
