✦ Synopsis

Singlet oxygenation of 1,1,2,2-tetramesityl-1,2-disilirane la 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.

Much attention has been drawn to the reaction of organosilicon compounds with molecular oxygen. West et al.
