METAL-HALOGEN INTERCHANGE BETWEEN t-BUTYLLITHIUM AND 1-IODO-5-HEXENES PROVIDES NO EVIDENCE FOR SINGLE-ELECTRON TRANSFER
No products attributable to cyclization of 5-hexen-1-yl radicals have been detected in reactions of t-butyllithium with 1-iodo-5-hexenes at -78 gradC.Such experiments provide no evidence for the intermediacy of free-radicals in the metal-halogen interchange of primary alkyliodides with t-C4H9Li.
