General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Iron(III) chloride may be employed for the synthesis of polypyrrole via polymerization reaction. It may be employed as catalyst for the intramolecular oxidative coupling for the preparation of phenanthrene ring. It is a cheap, eco-friendly oxidizing reagent useful for the following organic reactions:
  • polymerizations
  • oxidations
  • oxidative couplings
  • reductions
  • C-C bond formation
  • Ferrier rearrangement
  • multicomponent condensations
  • Friedel-Crafts reactions
  • cyclization′s
  • glycosidation
  • Prins-type cyclization
The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resitance properties.
