Abstract

The electron spin resonance spectra of the radical cations of dioxene (1 a), 2, 3- dimethyldioxene (1 b), 2, 3-diphenyldioxene (1 c), and benzodioxane (2) in fluid solution have been observed and analysed, with the help of ENDOR spectroscopy in the case of 1 c. It is concluded that in 1 c the molecule has overall C 2 molecular symmetry. In all four compounds, the pseudo-axial and pseudo-equatorial protons of the methylene groups in ...
