The Acidities of Nucleophilic Monofluoromethylation Reagents: …
15/02/2021· Fluorine incorporation into organic molecules is expected to lower the p Ka of neighboring functionality via its strong electron-withdrawing effect, and this strategy has been widely exploited in diverse disciplines. Herein, we report a striking anomalous α-fluorine substitution effect on the α-C sp3 -H acidity.
