Abstract

Regioselective cycloaddition of dialkylsilylene upon irradiation at 440 nm converts azulene and guaiazulene to bicyclic [4]dendralene and heptafulvene derivatives, respectively. Significant σ-π interactions in the resulting new silacycles were suggested using UV-vis spectra and theoretical calculations.
