摘要

Abstract Organosilyl potassium compounds are conveniently generated by cleavage of hexaorganodisilanes with potassium t-butoxide in common solvents other than HMPA (ie in THF or DME). Nucleophilic attack on unsymmetrical disilanes results in formation of the more stable silyl anion, ie the one with the most phenyl groups bonded to silicon.
