The oxythallation of certain 1,3-dienes with thallium(III) nitrate trihydrate in MeOH–CH2Cl2 at 0–20 °C gave products after vinyl migration. Methyl 1-methylcyclopropyl ketone, obtained in the reaction of 2,3-dimethyl-1,3-butadiene, was presumably derived from a cyclopropylmethyl cation, an intermediate in the vinyl migration.
