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.

Hazard

Highly toxic by ingestion, inhalation, and skin absorption; strong irritant.
