Silanes esters of 2,2,2-fluorodinitroethanol ROH have been prepared from chlorosilanes in approx. 90 yields. The non-compressive shock sensitivity of the high density 1.95 gcc, crystalline orthoester RO4 Si was clearly lower than that of RDX, but the calculated detonation velocities proved similar. Substantially higher boiling points at similar densities approx. 1.6 gcc relative to the reference compound FEFO were realized in the liquid esters RO3SiCH3 and RO2CH3SiOSiCH3OR2. The sensitivity of the thermally stable product esters toward hydrolysis by atmospheric moisture varied greatly. The energy contents Q of a number of silicon-containing structures were calculated.
