On irradiation, dibenzo-7-silanorbornadienes with bulkysubstituents on silicon generated the corresponding crowded silylenes that dimerized to kinetically stabledisilenes in the absence of trapping agents. Dibenzo-7-silanorbornadienes also underwent a new type of photochemical isomerization competitively.

The molecular structures of the 1-tert-butyl-1-isityl-3,3,3-triisopropyldisilaphosphene 4(isityl = 2,4,6-triisopropylphenyl), the analogous disilaarsene 5, and the corresponding tellura-arsasilirane 6(formed by reaction of 5 with elemental tellurium) are established by X-ray crystallographic analysis.
