General description
Mercury(II) chloride is an inorganic salt with the molecular formula HgCl2. Its vapor phase Raman spectra has been recorded and analyzed. The molecular structure of HgCl2 has been investigated based on the electron diffraction analysis data. The effect of strong acids on its stretching vibration frequencies has been studied.
Application
Mercury(II) chloride (HgCl2) has been used in a study to understand its toxic impact on rat cortical neurons.
It may be used as a catalyst for the addition reaction between aromatic amines and terminal acetylenes. It may also be used in the synthesis of [(HgCl2)2(HgCl2)(2-bppt)]n where 2-bppt= bis[4-(pyridine-2-yl)pyrimidin-2-ylthio]methane.
It assists in the following reactions:

It assists in the following reactions:
- Cyclization of amidinothioureas with phenyl hydrazine to afford 3-amino-1,2,4-triazole derivatives.
- Cyclization-rearrangement of O-propargyl glycolaldehyde dithioacetals leading to the formation of 3-pyranones.
- Reductive dimerization and cyclization of α,β-unsaturated ketones to generate 3,4-trans-diarylcyclopentanols.
Mercury (II) chloride can also be used as a catalyst for the:
- Addition reaction between aromatic amines to terminal acetylenes to give imines, enamines, and 1,2,3,4-tetrahydroquinoline derivatives.
- Cyclization of amidinothioureas with phenyl hydrazine to produce 3-amino-1,2,4-triazole derivatives.
- Cyclization of O-propargyl glycolaldehyde dithioacetals to afford 3-pyranones along with 2,5-dihydrofuran-3-carboxaldehydes through their dithioketals and dithioacetals reaction.
- Reductive dimerization and cyclization of α,β-unsaturated ketones produce functionalized cyclopentanols using N,N-dimethylformamide as solvent.
