Novel Photochemical Reactions of Dibenzodisilacyclohexadiene with Ketones

Article abstract of DOI:10.1246/cl.1987.983

Dibenzodisilacyclohexadiene reacts with ketones and formaldehyde, under photolytic coditions, to give a variety of products depending on the nature of the ketones used.A compound having 2-sila-3-oxabicyclo<3.2.2>nona-6,8-diene structure was isolated as a result of intramolecular trapping of a cyclohexadienyl radical.
