Electron transfer in nucleophilic aliphatic

Ashby, E. C. Sun, X. Duff J. L. Single-electron transfer in nucleophilic aliphatic substitution. Evidence for single-electron transfer in the reactions of 1-halonorbomanes with various nucleophiles./. Org. Chem. 1994, 59, 1270-1278. 

Despite the simmering debate within the community of physical organic chemists over the scope and importance of electron transfer in nucleophilic aliphatic substitution [356], evidence continues to accumiflate that electron transfer may play a role...
