Silicon chemistry: Come on silene
Neil Withers
Thermal rearrangement yields the first example of a bis-silene -- a
compound containing two carbon­silicon double bonds
© 2008 Wiley
Silenes are compounds that contain a carbon atom double-bonded to a silicon atom
and are quite rare -- indeed, the first stable one was only synthesized in 1982.
Silicon, like carbon, has four valence electrons with which to bond, but the difference
in electronegativity between the two means C=C double bonds are much more
common than Si=C. And whereas metal-substituted alkenes are common reagents,
no metal-substituted silenes are known.
Now, Yitzhak Apeloig, Dmitry Bravo-Zhivotovskii and colleagues from the Israel
Institute of Technology in Haifa (Technion) have prepared and characterized1
