Soc. 1978, 100, 5408.(4) Brown, HC" The Nonclassical Ion Problem"; Plenum Press: New York, 1977. Brown, H. C. Tetrahedron 1976, 32, 179. This testfor extra stabili-zation is based on the ideathat, if the norbornyl nucleus is abnormally stable, it will place less electron demand on a methyl group attached to the cation center than will a normal secondary carbonlum ion.(5) Thus, although fert-butylchloride is~ 5 kcal/mol more stable than sec-butyl chloride, cyclohexyl chloride is5 kcal/mol more stable thanIts tertiary Isomer, 1-methylcyclopentyl chloride. 3 We regret that this comparison was stated Incorrectly (In Italics) on page 5411 of ref 3, although it was stated correctly In the abstract of that article and is shown correctly In Figure 3 on page 5412.
