Abstract

The irradiation of silyl‐substituted 1,4‐disila(Dewar‐benzene) 1 with light of wavelength λ > 320 nm in the presence of 2,6‐dimethylphenyl‐isocyanide or phenylacetylene produced 1,4‐bis(di‐tert‐butylmethylsilyl)‐2,3,5,6‐tetraethyl‐7‐(2,6‐dime‐thylphenylimino)‐1,4‐disilabicyclo[2.2.1]hepta‐2,5‐diene 5 or 1,4‐bis(di‐tert‐butylmethylsilyl)‐2,3,5,6‐tetraethyl‐1‐(2‐phenylethynyl)‐1,4‐disilacyclohexa‐2,5‐diene 6, respectively. The molecular structures of 5 and 6 were determined by spectroscopic data and X‐ray crystallography. © 2008 Wiley Periodicals, Inc.
