Abstract

(Chemical Equation Presented) Internal fusion: The stable fused tricyclic tetraalkyl disilenes cis-1 and trans-1 were synthesized as yellow and red-purple crystals, respectively (see picture). X-ray analysis has shown that the geometry around the Si=Si bond in trans-1 is unusually distorted, but is rather normal in cis-1. Disilene trans-1 isomerizes stereospecifically to a tetracyclic isomer by unprecedented addition of a Si-Si single bond to a Si-Si double bond.
