Abstract: | The preparation of 1,1-diphenyl-2-(2,4- and 2,6-dinitrophenylhydrazine) is described. Lead peroxide converts them into hydrazyl free radicals, but only the latter may be isolated in crystalline form. Ultra-violet and visible absorption spectra of hydrazines and hydrazyls are compared. |
