Efficient Nucleophilic Aromatic Substitution between Aryl Nitrofluorides and Alkynes
摘要:
The nucleophilic aromatic substitution reaction between electron-deficient aryl fluorides and terminal alkynes is shown to be efficiently promoted by sodium bis(trimethylsilyl)amide as a base. Moderate to excellent yields of 2-ethynylnitrobenzene products can be obtained under mild conditions.
