Abstract
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 alkynes.
