## Abstract The structures of cyclic polyketones, their hydrates and reduction products were studied in different solvents by ^13^C‐NMR. spectroscopy. In dimethylsulfoxide solution rhodizonic acid **(1)**, croconic acid **(2)** and squaric acid **(3)** exhibit signal averaging. In anhydrous tetrahy
## Abstract The study of a set of 3‐benzylidene‐4‐chromanones, 3‐benzyl‐4‐chromanones, 3‐benzyl‐3‐hydroxy‐4‐chromanones and 3‐benzylchromones (homoisoflavonoids) by ^13^C NMR spectroscopy shows the influence of the structure of these molecules on the chemical shifts of the more characteristic carbo
