Abstract
The ^1^H NMR spectral analysis of four 8βmembered rings, 2βthioxoβ (or 2βoxoβ) 2βRβ1,3,6,2β trithiaphocane, is reported. The stereochemistry of the 8βmembered ring is discussed. The ^31^P NMR spectral parameters [Ξ΄^31^P, ^1^J(PC)] obtained on several cyclic 1,3,2βdithiaphospha compounds of variable size (5, 6, 8, 12 and 16βmembered rings) are discussed as a function of the ring size and of the geometry of the molecule.
