Application

4,4′-Di-tert-butyl-2,2′-dipyridyl can be used as a ligand:      
  • In the synthesis of oxidovanadium(IV) complex [VOCl2(dbbpy)(H2O)], which is used as a catalyst for the epoxidation of cyclooctene in the presence of tert-butyl hydroperoxide.     
  • In iron-catalyzed ortho-allylation of 1-arylpyrazoles via C-H activation.     
  • In iridium-catalyzed borylation of (hetero)arenes.      
  • In iron-catalyzed arylation of heterocycles in the presence of metallic Mg.      
  • In nickel-catalyzed decarboxylation of block copolymers.

Articles

Tools and techniques for performing atom transfer radical polymerization (ATRP) with benefits and limitations.

Arylboronic acids and esters are invaluable tools for the chemical community. These powerful reagents are used for a variety of transformations, most notably the Suzuki-Miyaura cross-coupling reaction.

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.

We presents an article about Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands, and the emergence of living radical polymerization mediated by transition metal catalysts in 1995, which was a seminal piece of work in the field of synthetic polymer chemistry.

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.

Sigma-Aldrich presents an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.

Sigma-Aldrich presents an article about the typical procedures for polymerizing via ATRP, which demonstrates that in the following two procedures describe two ATRP polymerization reactions as performed by Prof. Dave Hadddleton′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.
