In organic chemistry, sultones are cyclic sulfonate esters of hydroxy sulfonic acids that exist mainly as four-, seven-, and sometimes five-membered rings.[1] They are often short-lived intermediates, used as strong alkylating agents to introduce a negatively charged sulfonate group.
In the presence of water, they slowly hydrolyze to their respective corrosive hydroxy sulfonic acids. Sultones decompose when heated to produce toxic, foul smelling, sulfur dioxide fumes.[2][3]
Sultone oximes are key intermediates in the synthesis of the anti-convulsant drug zonisamide.[4]
Sultones are classified as toxic, carcinogenic, mutagenic, and teratogenic.[5][6][7]
