Abstract

Summary Analysis of the inversion barriers of cyclopentyl, cyclohexyl, and cycloheptyl radicals suggest that they are closely related to those of their parent hydrocarbons. In the fiveand seven-membered rings the 8-hydrogens are magnetically inequivalent in pairs but can be “exchanged “by a mechanism which probably involves pseudorotation. Like its parent hydrocarbon, the six-membered ring can only achieve such an exchange by a true ...
