✦ Synopsis

Various radical cations, in which two terminal 1,4dimethoxybenzene units are anellated to [2.2]paracyclophane (2b

and anthracene bridges (5 •+ ), have been studied by ESR and ENDOR spectroscopy. In the syn-and anti-naphthalenophane radical cations 2b •+ and 3b •+ the delocalization of the unpaired electron over both π-moieties and the distinct difference between the first and second oxidation potentials,

In the electron impact mass spectra of N,N′-diaryl-1,3-phenylenediamines, recorded under conditions generating the molecular ion as a base peak, the most important step involve a β-aromatic cleavage with H rearrangement, leading to the expulsion of a neutral arylamine; this fact can be used in meta isomer identification since for the corresponding 1,2- and 1,4-isomers the expulsion of an aryl radical is a competitive process
