General description

Gallium(III) iodide is a high melting pointinorganic solid with low volatility. It is used in various fields such as the production of semiconductors, gallium nitride crystals, and organic synthesis.

Application

Gallium(III) iodide can be used:
  • As a catalyst for Biginelli-type reaction to synthesize dihydropyrimidine-2(1H)-one derivatives.
  • As a reagent for the stereoselective synthesis of (Z)-β-iodo Baylis–Hillman adducts and for the aza-Prins cyclization.
  • As a precursor to synthesize highly crystalline gallium nitride crystals for energy conversion devices.
  • As a starting material to synthesize high-purity chalcogenide glasses.
