Uses

Methyltrioxorhenium(VII) is used as a catalyst for various transformations such as olefin metathesis. It is associated with hydrogen peroxide and used as an oxidizing agent. It is used to prepare acid or ester from the corresponding terminalalkynes. It is a catalytic oxidant used with urea hydrogen peroxide to prepare nitrones. It reacts with 2-methylnaphthalene to get 2-methyl-1,4-naphthoquinone (Vitamin K3). Further, it catalyzes the reaction with aldehydes and diazoketones to get an alkene. In addition to this, it is used as an effective antioxidant under various conditions.

Uses

Potent catalytic oxidant for converting alkenes to epoxides in a variety of solvents and 2-methylnaphthalene to 2-methyl-1,4-naphthoquinone (Vitamin K₃).
Catalytic oxidant used with urea hydrogen peroxide in an efficient conversion of imines to nitrones.
An effective antioxidant under various conditions.

Synthesis

Turn to light yellow to stop the reaction, lower the temperature, the reaction will be pumped filter, slag with a small amount of acetonitrile rinse, the filtrate was moved to the distillation sublimator filled with Ar gas, connected to the vacuum pump and low-temperature cooling circulating pump, distillation of acetonitrile at 30mm-Hg at 40 ?? -35 ?? condensation recovery of acetonitrile, when the distillation is carried out to the solid of oily liquid on the sublimator appeared to stop the distillation, the installation of sublimation of the inner tube in the 0.1mm -Hg70 ?? for sublimation processing, the resulting product methyl rhenium trioxide by re-sublimation to obtain refined methyl rhenium trioxide 1.86 g. The resulting refined methyl rhenium trioxide by melting point determination, the melting range is 105 ~ 106 ??.
