Synthesis of 4-(2-fluorophenyl)-7-methoxycoumarin: experimental and computational evidence for intramolecular and intermolecular C–F···H–C bonds
4-(2-Fluorophenyl)-7-methoxycoumarin (6) was synthesized by Pechmann reaction under mild conditions via a three-step reaction. The solution-state (1)H NMR spectra of 6 showed a strong intramolecular interaction between F and H5 (J(FH) = 2.6 Hz) and (13)C NMR suggested that this C–F···H–C coupling is...
