摘要：

We have developed protocols for promoting redox reactions utilizing the 2-substituted 1,3-dimethylbenzimidazoline (BIH-R) and benzimidazolium (BI*-R) couples which were applied to the desulfonylative radical Truce-Smiles rearrangement. Expected rearrangement products formed in modest to good yields in these processes, in which added or in situ generated BIH-R serve as electron-and hydrogen-atom-donating reagents or photocatalysts. DFT calculations were carried out to gain the information about the radical intermediates involved in the rearrangement reaction.
