Nonafluorobutanesulfonyl azide is an advantageous alternative to triflyl azide for the efficient synthesis of sulfonyl azides from sulfonamides in terms of its higher reactivity, lower cost, and non‐hazardous nature. The reagent has proven its utility in a novel synthesis of N,N′‐disulfonylamidines from available sulfonamides by a copper‐catalyzed two‐step, one‐pot sequential process with added terminal
九氟丁烷磺酰基叠氮化物因其较高的反应性,较低的成本和无害的性质,是从磺酰胺有效合成磺酰基叠氮化物的三氟叠氮化叠氮化物的有利替代品。该试剂已证明可通过铜催化的两步,一锅法连续反应,并添加末端炔烃,从现有的磺酰胺中合成N,N'-二磺酰lam胺类化合物。
