The cobalt-catalyzed regioselective C-H alkoxylation of 1-naphthylamide with diols through a bidentate-chelation assistance has been developed. In this transformation, not only linear diols, but also branched diols and oligoethylene glycols were tolerated under current reaction conditions, affording the corresponding hydroxyalkyl aryl ethers. In addition, control experiments suggested that picolinoyl was the key directing group, and furthermore, this C8-H alkoxylation reaction might proceed through a single-electron-transfer (SET) process.

1-萘酰胺衍生物与二醇的钴催化区域选择性交叉脱氢CO偶联

已经开发了通过二齿螯合助剂的钴催化的1-萘酰胺与二醇的区域选择性CH烷氧基化反应。在该转化中，在当前反应条件下不仅耐受直链二醇，而且耐受支链二醇和低聚乙二醇，得到相应的羟烷基芳基醚。另外，对照实验表明，吡啶甲酰基是关键的导向基团，此外，该C8-H烷氧基化反应可能通过单电子转移（SET）过程进行。
