2,2-Diphenyl-1-picrylhydrazyl (DPPH) is an intensely coloured organic stable free radical with paramagnetic and redox properties. In this work we present three new derivatives of DPPH, in which an amino substituent was designed for one of the p-phenyl position. The synthetic details and the structural characterizations of the compounds are shown.
