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 generate an iminium salt (Vilsmeier reagent). The reaction avoids the use of metal catalysts and hazardous reagents, and the desired N -sulfonylformamidines were obtained in 60% to quantitative yields.

A solvent-free green synthesis of N-sulfonylformamidines is reported via the direct condensation of N,N-dimethylformamide dimethyl acetal (DMF-DMA) and sulfonamide derivatives at room temperature. The described method avoids the use of metal catalysts as
TRICHLOROMETHYL GROUP AS A NUCLEOFUGE IN THE REACTION OF AZOMETHINES WITH AMINES
Krasnov, V.L.,Vasyanina, G.I.,Bodrikov, I.V.
, p. 1359 - 1362 (2007/10/02)
In the reaction of N-(2,2,2-trichloroethylidene)-4-R-benzoylsulfonamides (R = H, Cl, CH3) with aliphatic secondary amines N,N-dialkyl-N'-arylsulfonylformamidines are formed as substitution products of the trichloromethyl group.Thus, the trichloromethyl gr
