Electrophilic derivatives of 4-nitro-benzofurazan with different reactivities were used to synthesize 28 new mono- and disubstituted 4-amino-7-nitrobenzofurazans 2b, 2d, 2f-2i, 2l, 2m-2n, 3b-3f, 3h-3j, 4c-4d, 4f-4k, 4m, 4o-4p.A reaction mechanism is proposed on the basis of the differences of the reactivities and a preliminary kinetic examination.The acid character of the N-H-function in monosubstituted compounds is demonstrated by means of spectroscopical investigation of pKa-values.Data from i.r., u.v./vis, and fluorescence studies are offered.
