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.
We describe the facile preparation of novel, optically active nitridomanganese(V) complexes which serve as reagents for the electrophilicamination of sulfides. This amination method has several appealing features, including: i) the facile preparation of large quantities of the starting nitridomanganese reagent 3, ii) the preparation of acylsulfilimines 2 in optically active form, and iii) the mild
