CN cross‐coupling of aryl chlorides with hydrazine is described. Through the use of continuous flow, the hazards associated with the use of hydrazine in the presence of transition metals are decreased. In addition, multistep flow sequences have also been developed for the generation of functionalized heterocycles utilizing the arylhydrazine intermediates.
最小化风险:描述了通过芳基氯与肼的CN交叉偶联合成芳基肼的方法。通过使用连续流动,减少了在过渡金属存在下使用肼的危害。另外,还开发了多步流动顺序以利用芳基肼中间体产生官能化的杂环。
