A formal metal-free N-arylation of aromatic aldehydes with 3-azido-N-tosylpropan-1-amine through the Schmidt process was realized in the presence of acids. TfOH was found to be a good promoter, and the exclusive 1,2-aryl migration was observed. Furthermore, the conversion of an aliphatic aldehyde to the N,N-disubstituted formamide was achieved in excellent yield.
在酸的存在下,通过施密特方法实现了芳香醛与3-叠氮基-N-甲苯磺酰基丙烷-1-胺的无金属形式的N-芳基化反应。发现TfOH是良好的促进剂,并且观察到排他的1,2-芳基迁移。此外,以优异的产率实现了脂族醛向N,N-二取代甲酰胺的转化。
