Conformations of Cycloalkenyl Radicals: a Dynamic EPR Study of the Cyclohept-4-enyl Radical
Walton, John C.
, p. 412 - 415 (1988)
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 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.
