“…4,4',6,6-Tetranitro-2,2'-azotoluene (5) and 2,2',6,6'Tetranitro-4,4'-azotoluene (6) The electrochemical reduction of TNT, while capable of producing 6 in analytical quality, was tedious and not suited to prepare isomers of 6 (Brand and Eisenmenger, 1916;Sitzmann, 1974). In recognition of this, Sitzmann attempted the preparation of 6 by controlled oxidation of 4 with meta-chloroperbenzoic acid (mCPBA).…”
