  reactions of amines/amides with alcohols in the past. By employing the aerobic relay race methodology with Pd‐catalyzed aerobic alcohol oxidation being a more effective protocol for alcohol activation, ligand‐free homogeneous palladiums are successfully used as active catalysts in the dehydrative N‐alkylation reactions, giving high yields and selectivities of the alkylated amides and amines.

  可能是因为均相钯催化剂不是典型的借用氢催化剂，因此配体在常规厌氧条件下不能有效活化催化剂，因此过去从未将其用于胺/酰胺与醇的N-烷基化反应中。通过采用好氧接力竞赛方法，并以Pd催化的好氧醇氧化作为更有效的醇活化方案，无配体的均相钯已成功地用作脱水N-烷基化反应中的活性催化剂，从而提供了高收率和高选择性的烷基化酰胺和胺。机理研究表明，该反应很可能是通过我们最近发现并提出的新型中继竞争机制进行的。
