We synthesized various carbazoles from anilines through a three-step process with good overall yields (up to 48%). This process comprises N-acetylation, copper(0)-mediated Ullmann homocoupling, and acid-mediated intramolecular amination. It permits v

N-Sulfonylformamidines were synthesized from N-sulfonylsulfonamides by reacting with p-toluenesulfonyl chloride (TsCl) and N,N -disubstituted formamides. In this reaction, it was expected that mixing TsCl with the N,N-disubstituted formamide would ge
