PEROXIDES OF STERICALLY HINDERED DERIVATIVES OF SCHLENK HYDROCARBON DIRADICAL

Reaction of oxygen with three sterically hindered derivatives of Schle nk hydrocarbon diradical gives predominantly cyclic peroxides with cro ss-conjugated pi-systems. For mesitylene-based diradical 3, significan tly different yields of the cyclic peroxide for the reactions in the s olid state vs solution were obtained. In the absence of crystallograph ic studies for Schlenk hydrocarbon and its derivatives, X-ray crystall ography for peroxide 1A-O-2 supports the structural assignment for the corresponding diradicals.
