Abstract
The present invention is a method for synthesizing polynitropolyphenyls, and more particularly 2,2′,2″,4,4′,4″,6,6′,6″-nonanitroterphenyl (NONA), that employs only a dihalotrinitrobenzene as a starting material. The general method comprises reacting copper dust with dihalo-trinitrobenzene to form a dihalo-polynitropolyphenyl product. This product is then reduced through a high-yield conversion by heating it within a solvent with a reagent capable of providing a source of iodide and a proton source.
