Photolysis of anti-dodecaalkyltricyclo[4.2.0.0(2,5)]octasilane: Generation and reactions of cyclotetrasilene
The photolysis of tricyclic ladder oligosilanes gave a cyclotetrasilene intermediate, which was trapped by methanol, 2,3-dimethyl-1,3-butadiene, and anthracene. Anthracene underwent a cycloaddition with the cyclotetrasilenes at the 9,10- and 1,4-positions depending on the substituents on the cyclotetrasilene rings.
