Abstract

The reaction of (trimethy1tin) sodium with exo-5chlore and 5-bromo-2-norbomenea, endo- 5bromo-2-norbomene, and 3-bromo-and 3-iodonortricyclene in tetrahydrofuran has been examined. Use of dicyclohexylphosphine as a trap for intermediate radicals by hydrogen atom transfer showed that the bromides and chloride reacted predominantly by way of free- radical intermediates and by geminate reactions. The geminate products showed ...
