Inversion Barrier of the Cycloheptyl Radical

Abstract

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 five-and seven-membered rings the β-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 inversion of the ring. © 1985, American Chemical Society. All rights reserved.
