A Co(II)-catalyzed synthesis of sulfonyl guanidines by using amines, isonitriles, and organic azides as nitrene sources has been developed. This protocol provides an environmentally friendly and simple strategy for the synthesis of sulfonyl guanidine derivatives by employing a range of substrates and will find potential applications in organic synthesis. The computational and EPR studies suggested
The reaction between isocyanides 1, anilines 2, and chloramine T (3) affords N-sulfonylguanidines4. The reaction mechanism is discussed in the light of experimental evidences that confirm the initial formation of N-chloroanilines.
