CuCl/CCl4-Promoted Convenient Synthesis of Sulfonyl Amidines from Tertiary Amines and Sulfonyl Azides
摘要:
Promoted by CuCl/CCl4, a variety of sulfonyl azides and tertiary amines were successfully coupled to give sulfonyl amidine derivatives in good to excellent yields. A possible mechanism for this reaction is discussed.
Several of N‐sulfonylformamidines were synthesized in one‐pot using easily available sulfonyl chlorides, sodium azide and tertiary/secondary amines in the presence of 5 mol‐% CuBr2 in DCE under aerobic oxidative conditions.
