Aromatic sulphonyl azides react readily with unstrained olefins to give imines ⇌ enamines which, on hydrolysis, give the corresponding sulphonamide and ketone. In some cases, rearrangement occurs during the nitrogen elimination step. Reduction of the imines in situ with sodium borohydride leads to the arenesulphonamides in good yield.
芳族磺酰叠氮化物容易与未应变的烯烃反应,生成亚胺⇌烯胺,水解后得到相应的磺酰胺和酮。在某些情况下,重排发生在除氮步骤中。用硼氢化钠原位还原亚胺导致芳烃磺酰胺的收率良好。
