C–C Bond Cleavage at the N-α Position Enabled by the Low-potential Electrochemical Oxidation of the 2,7-Dimethoxynaphthyl Electroauxiliary (Supporting Information)

Herein, we report that the 2,7-dimethoxynaphthyl (2,7-DMN) group is a novel electroauxiliary that is readily installed at the N-α position of a carbamate through Friedel–Crafts-type arylation. The resulting N-α C–C bond is easily cleaved through low-potential electrochemical oxidation to give the corresponding iminium cation.本项研究中，我们报告指出，2,7-二甲氧基萘基（2,7-DMN）基团是一种新型的电辅助基团，能够通过Friedel-Crafts型芳基化反应轻易地安装在脒基的N-α位置。由此形成的N-α C-C键可通过低电位电化学氧化轻易断裂，从而得到相应的亚胺阳离子。
