Chlorure de mercure (II), réagentplus (R), 9

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: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.

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.
