Direct evidence explaining why 2-propynamides have never been used as substrates in Tf₂O-promoted electrophilic activations was obtained. Furthermore, a new method for the synthesis of structurally special 2,4-disubstituted quinolines was developed, by which the substituent at position 2 of quinolines can be diversified easily.

Tf2O 促进 2-丙酰胺的亲电活化和 2,4-二取代喹啉的新合成的机理洞察

获得了直接证据来解释为什么 2-丙炔胺从未用作 Tf ₂ O 促进的亲电激活中的底物。此外，还开发了一种合成结构特殊的2,4-二取代喹啉的新方法，该方法可以很容易地实现喹啉2位取代基的多样化。
