Description générale

Zinc iodide is a white crystalline Lewis acid often used as a starting material for synthesizing other zinc compounds, as a Lewis acid catalyst in organic reactions, and as an electrolyte additive.

Application

Zinc iodide can be used:
  • As a catalyst for one-pot synthesis of aminoindolizines via sequential A3 coupling/cycloisomerization.
  • As a catalyst for one-pot synthesis of quinoxalines.
  • As a precursor to synthesize highly luminescent quantum dots.
  • As a redox electrolyte in hybrid energy storage systems.
  • As a dopant to prepare highly flexible PVA composite films. The addition of zinc iodide enhances the optoelectronic properties of polymer composite.
