| | MERCURY(II) FLUORIDE Usage And Synthesis |
| Chemical Properties | yellow to pink powder | | Uses | Synthesis of organic fluorine compounds. | | Uses | Mercury(II) fluoride is a selective fluorination agent. Organic compounds, such as triphenylacetic acid, triphenyl ethylene, and triethyl phosphite can be selectively fluorinated in dimethylsulfoxide/HgF 2 solutions under UV-visible illumination. CF2I2 was synthesized by fluorination of tetraiodomethane with mercury(II) fluoride and purified. | | Preparation | Mercury(II) fluoride, HgF2, is most commonly prepared through the reaction of mercury(II) oxide with hydrogen
fluoride.
HgO + 2HF→HgF2 + H2O
It can also be produced through the fluorination of mercury(II) chloride.
HgCl2 + F2→HgF2 + Cl2 | | Hazard | Highly toxic by ingestion, inhalation, and
skin absorption; strong irritant. | | reaction suitability | reagent type: catalyst
core: mercury |
