Cover Feature: Isomerisation of Vinyl Sulfones for the Stereoselective Synthesis of Vinyl Azides (Eur. J. Org. B The Cover Feature b shows a kinetically controlled process where Green represents "go to Z (cis)" and Red represents "don't go to E (trans)" for the isomerisation of a series of 3-azido E-vinyl sulfones. This process has been studied, and on treatment with the base DBU it has been found that, for most structural variations, these vinyl sulfones selectively generate Z-vinyl azides.
