General description

Iron(III) chloride is a mild oxidizing agent. It is widely employed as a Lewis acid in organic synthesis. On crystallization with water, it forms hydrates. It can be prepared by passing chlorine over scrap iron at approximately 650°C.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. The iron catalysts are known to be inexpensive and environmentally benign. Click here for more information.

Application

Iron(III) chloride may be used for the polymerization of pyrrole and for the preparation of the phenanthrene ring. It is widely employed for the following reactions:
  • polymerizations
  • oxidations
  • oxidative couplings
  • reductions
  • C−C bond formation
  • Ferrier rearrangement
  • one-pot multicomponent condensations
  • Friedel-Crafts reactions
  • cyclization′s
  • glycosidation
  • Prins-type cyclisation
