General description
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.
