13 C NMR spectra of 39 thiophene and furan chalcone analogues in CDCl 3 solutions are reported. The effect of substituents on the 13 C chemical shifts in the phenyl and in the 5‐membered rings is discussed. 13 C NMR shifts are correlated with Hammett parameters and with experimental shifts in the chalcone series.
