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.

In two different types of reactions the title group behaves as a bulkier group than 2,4,6-tri-t-butylphenyl which has often been used for kinetic stabilization of highly reactive compounds.
