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 (FeCl3) can be used as a catalyst:
  • For the oxidation of glucose to gluconic acid in water.
  • To synthesize 2-iodo substituted benzo[b]thiophenes by iodocyclization of 2-alkynylthioanisoles in the presence of sodium iodide and ethanol as a solvent.
  • In the glycosylation sugars in the presence of allyl and alkynyl alcohols to synthesize corresponding glycosides.
  • To prepare 1,2-trans glycosyl azides by azido glycosylation of glycosyl β-peracetates.
