Facile generation of a strained cyclic vinyl cation by thermal solvolysis of cyclopent-1-enyl-λ3-bromanes

Last of the cyclic vinyl cations: The simple solvolysis of cyclopent-1 -enyl-13-bromane efficiently generates the highly strained cyclopent-1 -enyl cation at room temperature (see scheme). The very high nucleofugality of the aryl-13-bromanyl groups are re

Oxygenated phenanthrenes via quinol ketals: Cyclization vs. migration

2-methoxyphenanthrenes were prepared by reaction of lithiated 2-bromostyrenes with quinone monoketals followed by acid-mediated cyclization of the resulting p-arylquinol ketals. Substitution at the bromostyrene side-chain or the quinone monoketal ring had only a modest effect on yields, but oxygen substitution on the bromostyrene aromatic nucleus resulted in a competing 1,2-aryl migration arising during the quinol ketal cyclization step. The extent of this rearrangement was found to be a function of the Lewis acid/solvent system employed.
