The reactions of pure cis- and trans-3,4-benzo-1,2-di(tert-butyl)-1, 2-dimethyl-1,2-disilacyclobut-3-ene (1a and 1b) with oxygen in the presence of AIBN proceeded stereospecifically to give the respective siloxanes. The palladium-catalyzed reactions of 1a and 1b with phenylacetylene and 1-hexyne produced stereospecifically cis- and trans-5,6-benzo-1,4-disilacyclohexa-2,5-dienes.
