N-(2,6-Dimethylphenyl)-4-methylbenzenesulfonamide

Abstract

In the title compound, C15H17NO2S, the mol­ecule is bent at the S atom, the C—SO2—NH—C torsion angle being 88.0 (2)°. The dihedral angle between the two aromatic rings is 49.8 (1)°. In the crystal, mol­ecules are linked into zigzag chains parallel to the a axis via N—H⋯O hydrogen bonds.

Study of TiO2 nanoparticle phase alteration and its catalytic effect on the chemoselective N-sulphonylation of amines and urazoles

“…Interestingly, it was observed that the N -sulphonylation of urazoles proceeds in high yields and only mono-sulphonylated products were produced (table 1, entries [16][17][18].…”

“…The products were characterized on the basis of their spectral (IR, NMR) and melting points and compared with literature. 7,[14][15][16][17][18][19][20][21] Formation of expected sulphonamides is evidenced by disappearance of single and strong absorption band for N-H stretching bond and appearance of two stretching bands for SO 2 group in their IR spectra.…”

“…All the products are known and the spectral data and melting points were identical to those reported in literature (table 1). 7,[14][15][16][17][18][19][20][21] Method B: To a mixture of amine or urazoles (1.0 mmol) and 4-toluenesulphonyl chloride (1.0 mmol) in EtOH (4 mL) was added TiO 2 P25-900 (0.07 g). Then, the resulting mixture was sonicated at room temperature for appropriate time (table 1).…”
