N,O-Bis(trifluoroacetyl)hydroxylamine as a Useful Electrophilic Nitrogen Source: Catalytic Synthesis of N-(Trifluoroacetyl)sulfilimines
摘要:
[GRAPHICS]In the presence of catalytic quantites of Cu(OTf)(2) the novel hydroxamic acid anhydride salt functions competently in the trifluoroacetamidation of sulfides to afford N-(trifluoroacetyl)sulfilimines. The salient features of this salt include its ease of synthesis from the inexpensive, commercially available starting materials trifluoroacetic anhydride and hydroxylamine hydrochloride.
