T. Khan et al., A novel route towards formylated 1,3-dithiole-2-thiones via an unprecedented allylic 1,4-diol rearrangement, CHEM COMMUN, (4), 2001, pp. 369-370
In the presence of perchloric acid, an unusual 1,4-aryl shift is observed f
or two electron-rich 4,5-bis[hydroxy(aryl)methyl]-1,3-dithiole-2-thiones; t
he X-ray crystal structure of compound 8 confirms the structural identity o
f the rearrangement product.
