(photosensitizer for CH bond cleavage reactions;1-6 solvent for metals to give amalgams which can act as selective reducing agents;8-19 heterogeneous catalyst poison, especially for Group 10 metal catalysts;22 electrode material in electrosynthesis24)
Physical Data: mp −38.87 °C; bp 356.6 °C; d 13.6 g cm−3.
Solubility: sparingly soluble in organic solvents and water.
Form Supplied in: silvery liquid; widely available; electronic grade (foreign metals ≤1 ppm) and ACS grade (99.9995%) are available, normally making purification unnecessary.
Handling, Storage, and Precaution: as a volatile heavy metal, care must be taken to prevent long term inhalation of the vapor. Carrying out reactions in a fume hood, cleaning up spills, and assuring that the air handling system of the laboratory is operating normally is generally sufficient.
