General description

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.


Iron(II) chloride can be used to catalyze:
  • The preparation of Grignard compounds, such as 1-naphthylmagnesium chloride.
  • The selective oxidation of 2,4,6-trimethylphenol (2,4,6-TMP) to 3,5-dimethyl-4-hydroxybenzaldehyde (DMHB) in the presence of acetoxime.
  • Raney-type catalysts modified with FeCl2 show enhanced selective hydrogenation of an α,β-unsaturated aldehyde to an unsaturated alcohol.

Diarylalkynes are chemo- and stereoselectively hydromagnesiated in high yields at room temperature with an iron species generated in situ from FeCl(2)and EtMgBr. Functional groups such as bromide, iodide, amine, phenoxide, and alkene are well tolerated. Under similar conditions, diynes are...
We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.
