Solvent-free synthesis of N-sulfonylimines using microwave irradiation
Vass, Andras,Dudas, Jozsef,Varma, Rajender S.
, p. 4951 - 4954 (1999)
N-Sulfonylimines are prepared expeditiously in a one-pot solventless operation by microwave thermolysis of aldehydes and sulfonamides in the presence of benign reagents, calcium carbonate and montmorillonite K 10 clay.

A palladium-catalyzed intramolecular amination of alkenes with retention of olefin functionalization was achieved under mild reaction conditions. In the presence of palladium catalyst, the tosyl-protected amine can directly couple with a double bond to provide versatile dihydropyrrole derivatives in moderate to excellent yields.
Preparation of N-arylsulfonyl imines from sulfonamides and aryl aldehydes using magnesium oxide as a heterogeneous and reusable catalyst under solvent-free conditions

An efficient solvent-free procedure for the preparation of N-arylsulfonyl imines from sulfonamides and aryl aldehydes in the presence of a catalytic amount of magnesium oxide and tetrabutylammonium bromide (TBAB) under microwave irradiation is described. The advantages of this method are good to high yields, short reaction times, low cost, and matching with green chemistry protocols. Copyright Taylor & Francis Group, LLC.
