The influence of substituents in a new series of 2 H ‐thiopyrans, 2 H ‐thiopyran‐2‐ones (thiones) and their thiazine analogues is examined by means of carbon ( 13 C) and nitrogen ( 15 N) NMR. A linear relationship is shown to exist between the chemical shifts (δ 13C or δ 15N ) of the thiopyrans and the thiazines. This relationship is a good indication of the structural similarity which exists between the two series.
