A solvent-free synthesis of N-sulfonylimines from aldehydes with sulfonamides is described using ZrO2/S2O2- 8 as catalyst under microwave irradiation. This method is fast and high yielding for a range of substrates.

Treatment of allenyl sulfonamides with catalytic amounts of silver fluoride in acetonitrile at reflux afforded the corresponding 3-sulfonyl-3-pyrrolines in excellent yields by intramolecular hydroamination via a 5-endo-trig cyclization. The starting allenyl sulfonamides were prepared by lithiation of allenic sulfones and trapping with various N-sulfonylimines.
