Article abstract of DOI:10.1016/0040-4039(95)01530-2

Five 3-alkyl- or 3-aryl-5,5,6,6-tetramethyl-1,2,4-trioxanes 4 upon treatment with iron(II) sulfate in aqueous acetonitrile under nitrogen for 12-72h are cleanly isomerised into the corresponding 2,3-dimethylbutan-2,3-diol monoesters 5; it is suggested tha
