Abstract

The 100 MHz spectrum of 1,3‐oxathiane‐3‐oxide is reported. Parameters obtained from first order analyses are interpreted in terms of an absence of a conformational preference of the SO bond at 38°C, but an axial preference at low temperatures. The behaviour contrasts with that found previously in the 1,3‐dithiane‐1‐oxide series.

## Abstract The preparation of 4‐phenyl‐1, 3‐oxathian, 6‐methyl‐1, 3‐oxathian, and some of their 2‐substituted derivatives is described. Significant features of their NMR spectra are discussed with particular reference to the influence of the heteroatoms on the coupling constants of adjacent proton
