internal and the terminal double bond in the octenes 2a-c and (Z)-1,10-nonadecadiene are evidence for a concerted cycloaddition of sulfurtrioxide. The formation of β-sultone 1d is accompanied by 15% of 2-octene-1-sulfonic acid, formed in a primary side-reaction. The sulfonation of the octenes 2a-d to their β-sultones 1a-d is reversible. Desulfonation of the β-sultones 1a-d by water to the olefins 2a-d

Sulfonation of 1-octene, ()-1-deuterio-1-octene, and ()- and ()-4-octene with one mol-equiv of sulfurtrioxide yields the β-sultones - respectively. The reaction proceeds stereospecifically a concerted -cycloaddition.
