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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
