Stereochemical outcome of benzyllithiums synthesis from selenides

Epimerisation usually occurs during the synthesis of arylalcanes from the corresponding benzylselenides which involves benzyllithiums as intermediates. This has been used to produce stereoselectively arylcyclopentanes and arylcyclopropanes. γ-Benzenesulfonyloxyalkyl selenides substituted on the carbon bearing the benzenesulfonyl group behave differently and lead stereospecifically to arylcyclopropane derivatives.
