Substituierte Alkylsulfonate durch Addition von Natriumhydrogensulfit an Chalkone

Substituted Alkyl Sulfonates by Addition of Sodium Hydrogen Sulfite to Chalcones Sodium hydrogen sulfite adds to the C, C double bond of chalcones to give substituted alkyl sulfonates 1. Reaction of methyl iodide with the pyridyl substituted alkyl sulfonates 1b–1e yields the inner salts 2–4 .
