efficiency on a graphite felt electrode coated with a thin poly(acrylic acid) layer immobilizing 4-amino-2,2,6,6-tetramethylpiperidinyl-1-oxyl (4-amino-TEMPO). 1-Naphthol and 1-methoxynaphthalene were also completely converted to the predicted 1,1′-, 1,2′-, and 2,2′- positioned coupling products. The reaction proceeds via electrocatalytic oxidation of the modified-TEMPO species. The electrode was not inactivated
2-萘酚和 2-甲氧基萘在石墨毡电极上以超过 90% 的电流效率被定量氧化为相应的 1,1'-联萘,该电极涂有固定 4-氨基-2,2 的聚(丙烯酸)薄层, 6,6-四甲基哌啶基-1-氧基(4-氨基-TEMPO)。1-萘酚和1-甲氧基萘也完全转化为预测的1,1'-、1,2'-和2,2'-定位偶联产物。该反应通过修饰的 TEMPO 物质的电催化氧化进行。电极在电解过程中未失活,可重复使用。
