Abstract: Three bis(trifluoromethyl) dinitrobiphenyls were prepared by heating chloro- or iodo-nitrobenzotrifluorides with copper in DMF. Three bis (trifluoromethyl)-dinitrodiphenyl ethers were obtained by the reactions of chloronitrobenzotrifluorides with alkali Metal carbonates in aprotic solvents.The dinitro compounds were reduced by tin and hydrochloric acid to give the corresponding diamino derivatives.The diisocyanates, 3, 3'-(CF0)2-4, 4'-(NCO)2- and 2, 2'-(CF0)2-4, 4'-(NCO)2-biphenyl, 3, 3'-(CF3)2- 4, 4'-(NC0)2-, 2, 2-(CF3)2-4, 4'-(NCO)2- and 4, 4'-(CF0)2-2, 2'-(NCO)2-diphenyl ether, were obtained by the reactions of the amine derivatives with phosgen in glyme.
