Hi,
i have p-aminobenzenesulfonamide with a stereocenter next to the nitrogen of the sulfonamide bond.
The h-nmr (CD3OD) shows a dt for all aromatic hydrogens. The XJ coupling constants vary on both sides of the triplett.
7.60 (dt, 2H, 3J = 8.7 Hz, XJ=1.8-2.8 Hz)
6.70 (dt, 2H, 3J= 8.7 Hz, XJ=2.0-2.8 Hz)
What kind of coupling is XJ and why is it a triplett?
Thanks a lot for your *delete me*
Chris
