Descripción

General description

Mercury (II) chloride is an inorganic salt commonly used as a catalyst in organic synthesis.

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.
