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.

Application

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.

Articles

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.

Protocols

We presents an article featuring procedures that describe polymerization of methyl methacrylate and vinyl acetate homopolymers and a block copolymer as performed by researchers at CSIRO.

We present an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.

Polymerization via ATRP procedures demonstrated by Prof. Dave Haddleton's research group at the University of Warwick.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
