Abstract The synthesis of 4,4′-di(methylamino)- and 4,4′-dianilino-3,3′-diaminobiphenyls is described. The condensation of the tetraaminobiphenyls mentioned with phenyl perfluorobutyrate has given, respectively, 1,1′-dlmethyl- and 1,1′-diphenyl-2,2′-(n-perfluoropropyl)-5, 5′-bibenzimidazolyls. A study of the thermal stability of the 2-perfluoroalkylbenzimidazoles has shown that the replacement of the hydrogen of the imino group in these compounds by a methyl or a phenyl radical considerably increases their heat stability.
