Abstract
Energetic silicon compounds of the general formulae ##STR1## The gem dinitro compounds are prepared from alkyl bromide silanes by sod nitrite displacement and oxidative nitration. The compounds are then fluorinated. To prepare the polysiloxanes, phenyl blocking groups are used during synthesis of the fluoro dinitro moiety and are then replaced with bromine and the monomer is hydrolyzed.
