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.
本发明涉及一种新型的能量取代二醚化合物的制备和以前未报告的新型二醚化合物。在一种实施方式中,某些同分异构体的二溴烷通过与三氟甲烷磺酸银(三氟甲烷磺酸酯)在各种溶剂中反应,转化为相应的溴代烷基三氟甲烷磺酸酯的同分异构体。然后,酯中的三氟甲烷磺酸酯基易被醇类取代,包括含有硝基的非亲核醇类。在温和条件下,中间体同样被反应制备成为具有能量取代的二醚化合物。这些能量取代的二醚化合物特别适用于火箭推进剂粘合剂的能量硫化剂和增塑剂,以及稳定的固体氧化剂和工业炸药。
