Complete assignments of the 1H and 13C NMR spectra of some fluoro‐substituted chromenes

Abstract
The total assignment of the 1H and 13C NMR spectra of four fluoro‐substituted chromenes was deduced from the concerted application of homonuclear correlation (COSY), 1H‐detected one‐bond heteronuclear multiple quantum coherence (HMQC) and long‐range (two and three bonds) heteronuclear multiple bond connectivity (HMBC) experiments.
