  The sequel to a carbocyclic nucleoside synthesis: a divergent access to both arenediazonium ions and aryl triflates

  摘要：

  Depending on the amount of acid used, treating aryl-dialkyl triazenes of general structure 3 with triflic acid resulted in the formation of either the corresponding arenediazonium triflates 4 or aryl triflates 8 apparently by two different pathways, the latter conversion being favoured at high acid concentration.

  An efficient and metal-free coupling reaction has been developed that affords acetamides from the corresponding aryl amines and acetonitrile. This method tolerates a wide range of functional groups and is selective toward aryl amines. Preliminary mechanistic studies were conducted.

  已开发出一种有效且无金属的偶联反应，可从相应的芳胺和乙腈中生成乙酰胺。该方法可耐受范围广泛的官能团，并且对芳基胺具有选择性。进行了初步的机理研究。

  A variety of stable, safe, and soluble arenediazonium triflates ArN2+ TfO– were obtained easily by diazotization of anilines with tert‐butyl nitrite in the presence of triflic acid. They are highly reactive, forming aromatic iodides, azides, and boronic acids, and also undergo an unusual metal‐free chloro‐dediazonization with chloroform and CCl4.

  在三氟甲磺酸存在下，通过亚硝酸叔丁酯对苯胺进行重氮化，可轻松获得各种稳定，安全且可溶的芳族二氮杂三氟甲磺酸盐ArN 2 +  TfO –。它们具有很高的反应活性，形成芳族碘化物，叠氮化物和硼酸，并且还与氯仿和CCl 4进行了不同寻常的无金属无氯二氮杂脱氮反应。
