## Abstract The results of a ^13^C NMR spectral investigation involving 5,6โdihydroโ1,4โoxathiins, 1,4โtetrahydro[9,10]benzoxathiin, __trans__โtetrahydroโ1,4โbenzoxathiin, and the corresponding sulfoxides and sulfones are reported. An interpretation involving a dipolar structure with (2__p__โ2__p__
The products of hetero-Diels ยฑ Alder reactions (sultines) and cheletropic addition reactions (sulfolenes) between 1,3-dienes and sulfur dioxide can be distinguished by their 17 O NMR shifts. Experimental data have been collected for derivatives of 3,6dihydro-1,2-oxathiin-2-oxide and of 2,5dihydrothi
