sulfonamide leads to displacement of the sulfonamide at the sp centre and isolation of the ynol ether in good yield in a single operation (see scheme). The mechanistic pathway has been probed by the use of coordinating additives, 13C‐labelling experiments and ab initio calculations, which indicated that an addition/elimination mechanism is in operation.

酰胺在sp中心发生置换,并在一次操作中以高收率分离出炔诺醚(请参见方案)。通过使用配位
添加剂,13 C标记实验和从头算计算已经探究了该机理途径,这表明添加/消除机理正在发挥作用。
