New Synthetic Techniques for Advanced Propellant Ingredients: Trifluoromethanesulfonate Derivitive Intermediates
Abstract
The metathesis reaction between silver triflate and bromoalkanes potentially offers an attractive synthetic complement to the well known alcohol condensation with triflic anhydride for organic triflate esters. Dibromoalkanes can further give difunctional triflate intermediates and could provide convenient routes to asymmetrically substituted derivatives. Certain shorter members of the alpha,omega-dibromoalkane homologous series display a unique reactivity and product selectivity over higher homologues and corresponding 1 monobromoalknaes. Triflate products from monobromoalkanes and alpha,omega- dibromoalkanes greater than 1,4-dibromobutane can lead to benzene solvent alkylation or polymerization in CC14, but the lower 1,2- through 1,4- dibromoalkanes produce desired monobromoalkyl triflate and akanediyl ditriflate products under the same reaction conditions. Keywords: Trifluoromethanesulfonate; Energetic materials; Propellants; Ingredients; Synthesis(Chemistry); Fluorodintroethyl; Nitrogen compounds.
