Description

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.
