Upon irradiation of a stable cyclotrisilene, 1,3,3-tris(tert-butyldimethylsilyl)-2-[tris(tert-butyldimethylsilyl)silyl]cyclot risilene (5), in toluene with a low-pressure mercury-arc lamp, the isomerization of 5 to hexakis(tert-butyldimethylsilyl)bicyclo[1.1.0]tetrasilane (2) occurred in high yield; 2 isomerized further to the corresponding cyclotetrasilene 1 by a thermal process as previously reported. The distance of the silicon-silicon double bond in 5 determined by X-ray crystallography (2.132(2) Å) was similar to those of the known stable disilenes.
