Hyperconjugative Antiaromaticity Activates 4 H -Pyrazoles as Inverse-Electron-Demand Diels–Alder Dienes
The Diels-Alder reactivity of 4,4-difluoro-3,5-diphenyl-4H-pyrazole was investigated experimentally and computationally with endo-bicyclo[6.1.0]non-4-yne. The computationally predicted rate enhancement from hyperconjugative antiaromaticity induced by fluorination of cyclopentadienes at the 5-positio...
