A novel route towards formylated 1,3-dithiole-2-thiones via an unprecedented allylic 1,4-diol rearrangement

In the presence of perchloric acid, an unusual 1,4-aryl shift is observed for two electron-rich 4,5-bis[hydroxy(aryl)methyl]-1,3-dithiole-2-thiones; the X-ray crystal structure of compound 8 confirms the structural identity of the rearrangement product
