Some organosilicon-substituted ketones have been converted into β-ketoesters, and hence into 4-derivatives of 7-hydroxycoumarin.
一些有机硅取代的酮已被转化为β-酮酸酯,因此被转化为7-羟基香豆素的4-衍生物。

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.
