Synthesis of N,3,5-Substituted 1,4-Phenylenediamines
N,3,5-Substituted 1,4-phenylenediamines were obtained by reduction of N,3,5-substituted 4-nitosoanilines by hydrazinehydrate on the Pd/C. N-((1-Аdamatyl)methyl)-3,5-substituted 4-nitrosoanilines were first synthesized by condensation of 2-hydroxyimino-1,3-diketone with acetone and (1-adamatyl)methanamine in pyridine.
