 Title    Factors Affecting Stability and Equilibria of Free Radicals, XVII+ EPR Evidence for Formation of N-AIkoxypicramides on Oxidation of N-Alkoxy-dinitroanilines. Electronic Structure of Aminyl Radicals  
 Abstract    Oxidation of N-alkoxy-2,6-or -2,4-dinitroanilines with various oxidizing agents yields the corre­ sponding N-alkoxydinitrophenyl-am inyls, which then undergo spontaneous conversion into the corresponding N-alkoxy-2.4.6-trinitrophenyl-am inyls. The EPR spectra o f all these persistent aminyls are presented and discussed. Such disproportionations did not occur in capto-dative diaryl-aminyls which had lower spin densities on the electron-acceptor group than the present N-alkoxy-polynitrophenyl-am inyls (these have, in addition, N —O bonds which are less strong than N —C bonds). Electronic structures o f diaryl-aminyls and N-alkoxy-aryl-aminyls are discussed: both are ;r-radicals, but they probably possess at the nitrogen atom an approximately linear, and a kinked structure, respectively.
