Full Title
Full titles differ between systems:
Amides of sulfonic acids, i.e. compounds having singly-bound oxygen atoms of sulfo groups replaced by nitrogen atoms, not being part of nitro or nitroso groups > Compounds containing any of the groups X being a hetero atom, Y being any atom > Y being a hetero atom > either X or Y, but not both, being nitrogen atoms, e.g. N-sulfonylurea > having sulfur atoms of the sulfonylurea groups bound to carbon atoms of six-membered aromatic rings > having nitrogen atoms of the sulfonylurea groups further acylated
