ABSTRACT:
Disclosed is a method of making 1,1'-sulfonylbis[3-nitro-5-(trifluoromethyl) benzene] by reacting dibenzotrifluoride sulfide with at least four equivalents of fuming nitric acid and at least four equivalents of fuming sulfuric acid at a temperature below 20.degree. C., until the sulfide link is oxidized to a sulfone link, then raising the temperature to above 20.degree. C. until the reaction is complete. Also disclosed is the preparation of 1,1'-sulfonylbis[3-nitro-(5-trifluoromethyl) benzenamine] by reducing the benzene compound.
