Application

Mercury (II) chloride can 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.

Mercury compounds exert toxic effects via interaction with many vital enzymes involved in antioxidant regulation, such as selenoenzymes thioredoxin reductase (TrxR) and glutathione peroxidase (GPx). Selenium supplementation can reactivate the mercury-inhibited TrxR and recover the cell viability in vitro. To
