Abstract

Cyclopent‐3‐enyl, cyclohex‐3‐enyl and cyclohept‐4‐enyl radicals were generated and their EPR spectra obtained in solution over a range of temperatures. The spectral data were consistent with a fully planar conformation for cyclopent‐3‐enyl radicals and a slightly flattened half‐chair conformation for cyclohex‐3‐enyl radicals. Cyclohept‐4‐enyl radicals showed exchange broadening in their EPR spectra which indicated inversion from one chair conformer to another with an Arrhenius activation barrier of 16.5 ± 0.3 kJ mol‐1.
