Thermal interconversion of allylic sulfoxides and SUlfenateS, eventually followed by nucleophilic decomposition of the latter to alcohols, has found wide application in organic synthesis1s2. Elimination of sulfenic acid from allylic sulfoxides or sulfenates to dienes does not seem to have found much synthetic use. An example of this type of elimination is suggested by Ultee and Louw3 as an explanation of the thermolysis of 4-methylsulfinyl-1- ...
