Abstract
In one study a disilene is prepared by an intramolecular coupling of a 1, 1-dibromosilane with potassium
graphite. The silicon double bond in the resulting compound has a bond length of 227 picometer (second
largest ever found) with trans-bent angles 33° and 31° (by X-ray diffraction).
In addition to this the substituents around the Si-Si bond are twisted by 43°. The disilene isomerizes to a
tetracyclic compound by heating at 110°C in xylene thereby releasing its strain energy. Siloles, also
called silacyclopentadienes, are members of a larger class of compounds called metalloles. They are the
silicon analogs of cyclopentadienes and are of current academic interest due to their electroluminescence
and other electronic properties. Siloles are efficient in electron transport. They owe their low lying
LUMO to a favorable interaction between the antibonding sigma silicon orbital with an antibonding pi
orbital of the butadiene fragment.
Keywords:
double bond, Siloles, silacyclopentadienes, electron transport.
