Abstract
The invention comprises a novel preparation of energetically substituted diether compounds and novel diether compounds not previously reported. In one embodiment certain isomeric forms of dibromoalkanes are converted to corresponding isomers of bromoalkyl trifluoromethanesulfonate esters by reaction with silver trifluoromethanesulfonate (triflate) in a variety of solvents. The triflate substituent in the bromoalkyl triflate esters is then easily displaced by alcohols, including non-nucleophilic ones such as those that contain nitro. The intermediates are similarly reacted to make energetic diethers, selectively under mild conditions. The energetically substituted diether compounds are particularly useful as energetic curatives and plasticizers for rocket propellant binders as well as stable solid oxidizers and industrial explosives.
