Thermal decomposition of 3,4-oxathiabicyclo[4.1.0]heptane 4-oxides into sulphur dioxide and a 1,4-diene. A novel π2s+π2s+π2s cycloreversion
Abstract
The thermolysis of the bicyclic sultines (12), (13), and (14) gives, smoothly and stereospecifically, a 1,4-diene and SO2via a novel concerted cycloreversion.
