Résumé
Although γ-sulfonyloxy-benzylselenides react with butyllithium to produce stereospecifically aryl cyclopropanes, the corresponding γ-silyloxy-benzylselenides lead to a stereoisomeric mixture of γ-hydroxy-α-silyl-benzylselenides via the retro-[1,4]-Brook rearrangement. Apparently the intermediate benzyllithiums are alkylated before epimerisation takes place in the first case, whereas in the second one epimerisation occurs prior to the silyl group migration.
