Abstract
[GRAPHICS] For reactions of magnesium with cyclopropyl bromide in diethyl ether, added DCPH decreases the yield of cyclopropylmagnesium bromide by as much as 75% , while solvent-derived products disappear and cyclopropylcyclohexylphosphi ne and tetracyclohexyldiphosphine appear. These changes reflect trapping of diffusing intermediate cyclopropyl radicals.
