✦ Synopsis

The "C n.m.r. spectra of 2-arylaminothiazoline, -tbiazine and -thiazepine derivatives, and also those of some N-substituted isomeric pairs were recorded and assigned. The structure of the individual isomers, which as a result of contradictory spectroscopic data had earlier been ambiguous, was established. In addition, the tautomeric structure of some N-unsubstituted compounds was determined.

The structures of the 2-arylaminothiazolines ( n = 2), -thiazines ( n = 3), and -thiazepines ( n = 4), which can be characterized by the tautomeric structures l a (R = H) and l b (R=H), as well as the possible isomers of , R'

## Abstract The isomer‐pairs of the 2‐arylamino‐2‐thiazolines and ‐thiazines, carrying a methyl substituent on the nitrogen atom of the ring and outside the ring were synthesised by unambiguous routes. An IR and NMR investigation of these compounds revealed the fact that the NMR signal of the 2,6‐s

## Abstract 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 t
