A novel intramolecular [2π+ 2π] photocycloaddition of di- and tetra-allylsilanes
Abstract
Irradiation of di- and tetra-allylsilanes in the presence of 1,4-dicyanonaphthalene (1,4-DCN) in benzene afforded the intramolecular [2π+ 2π] photocycloadducts in good yields via(1,4-DCN–C6H6–Si-compound) triplexes.
