Generation of C2F5CHN2 In Situ and Its First Reaction: [3+2] Cycloaddition with Alkenes
Chem. Eur. J. , 2014, 20 (17), 4942-4947
The novel chemical reagent, C2F5CHN2, is generated in situ from C2F5CH2NH2⋅HCl and sodium nitrite. It reacts with mono- and disubstituted electron-deficient alkenes at oom temperature to afford C2F5-pyrazolines in excellent yields.
