Single-electron transfer to iodides from sodium naphthalide and butyl-lithium
Abstract
A non-concerted single-electron transfer pathway has been established for the reductive elimination of α-iodo epoxides to allylic alcohols with sodium naphthalide; the exchange reaction between BuLi and RI must proceed exclusively by single-electron transfer to account for identity of rates of reaction between BuLi and epimeric 3-iodo-4β,5β-epoxycholestanes.
