Abstract
Abstract ( o -Halophenyl)trimethylsilanes afford products expected from the generation of 1,2-dehydrobenzene when treated with potassium tert-butoxide or tetramethylammonium fluoride in aprotic solvents such as hexamethylphosphoric triamide and diglyme. The dehalosilylation leading to 1,2-dehydrobenzene appears to proceed by a stepwise process which involves the initial formation of an o -halophenyl carbanion resulting from heterolytic cleavage of the aryl—silicon bond.
