Base-Free Method for Preparation ofO-Sulfonyl Aldoximes Starting from Aldoximes and Sulfonyl Chlorides

Abstract

A series of O-sulfonyl oxime derivatives have been synthesized by the reaction of oximes with sulfonyl chlorides in the presence of silver oxide and potassium iodide. In the case of aromatic aldoximes and ketoximes, desired products were obtained in 56%～87% yields. But then no desired products were obtained when p-nitrobenzaldoxime, aliphatic aldoximes and α,β-unsaturated aldoximes were employed as substrates in the process.
