Usage And Synthesis

Description

The manganese fluoride, MnF3, is preferably formed by fluorination of manganese(III) iodide. It is a solid, and although its decomposition pressure is lower than 10.1325kPa (0.1 atmosphere) at 600°C, fluorine is still released when heated. It is a strong fluorinating agent, which acts with sulfur, boron, silicon, carbon, phosphorus trichloride and carbon tetrachloride when heated. It is used to fluoride gaseous hydrocarbons.

Chemical Properties

purple powder or crystals

Uses

It is used as a fluorinating agent, useful for conversion of hydrocarbons into fluorocarbons. It is used in organic synthesis as Lewis acid to prepare a number of organic compounds.

Uses

Fluorinating agent in organic chemistry.

Preparation

Manganese(III) fluoride can also be formed via the reaction of elemental fluorine with a manganese(II) halide at around 250°C.

General Description

Manganese(III) fluoride (also known as manganese trifluoride), MnF3, is a red/purplish solid useful for converting hydrocarbons into fluorocarbons, that is, it is a fluorination agent. It forms a hydrate and numerous derivatives. MnF3 can be produced by reacting a solution of MnF2 in hydrogen fluoride with fluorine.

Hazard

Toxic material.

reaction suitability

reaction type: C-H Activation
reagent type: catalyst

Synthesis

Dissolve Mn2O3 in hydrofluoric acid and concentrate the solution for crystallization, or reduce potassium permanganate in hydrofluoric acid with low manganese salt to obtain hydrated manganese fluoride MnF3·3H2O. This compound is soluble in cold water and does not decompose, and is stable in hot water in the presence of hydrofluoric acid. Anhydrous manganese trifluoride is slowly decomposed into manganese difluoride, hydrated manganese dioxide and hydrogen fluoride in water.
