C07C311/57 - CPC Classification

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

• C07C311/58 » having nitrogen atoms of the sulfonylurea groups bound to hydrogen atoms or to acyclic carbon atoms 24
• C07C311/59 » having nitrogen atoms of the sulfonylurea groups bound to carbon atoms of rings other than six-membered aromatic rings 11
• C07C311/60 » having nitrogen atoms of the sulfonylurea groups bound to carbon atoms of six-membered aromatic rings 19
• C07C311/61 » having nitrogen atoms of the sulfonylurea groups further bound to another hetero atom 2
