Homogeneous Cu/TEMPO catalyst systems (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) have emerged as some of the most versatile and practical catalysts for aerobic alcohol oxidation. Recently, we disclosed a (bpy)Cu(I)/TEMPO/NMI catalyst system (NMI = N-methylimidazole) that exhibits fast rates and high selectivities, even

Block copolymer synthesis using a commercially available nitroxide-mediated radical polymerization (NMP) initiator

TEMPO(2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基)及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现,其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。

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.

实验方案

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.

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.
