Reaction Of N-halosulfoximines With Disulfides
Published 1985 · Chemistry
Abstract The reaction of S,S-diphenyl-N-chloro-(1), S,S-diphenyl-N-bromo-(2), and S-methyl-S-phenyl-N-chloro-sulfoximine (5) with disulfides in refluxing carbon tetrachloride was found to afford the corresponding sulfoxides. In the presence of pyridine, 1 and 2 reacted with disulfides at room temperature to give the corresponding bis-diphenylsulfoximinyl alkyl or aryl sulfonium halides arising from the reaction of the intermediary N-sulfenylated sulfoximine and the starting N-halosulfoximine.
