Abstract
A Cu(OTf)2-catalyzed trifluoroacetamidation of sulfides with a hydroxamic acid anhydride salt provides N-(trifluoroacetyl)sulfilimines. The salient features of this salt include its ease of synthesis from trifluoroacetic anhydride and hydroxylamine hydrochloride as inexpensive, commercially available starting materials.
