Determination of Rate Constants for the Activation Step in Atom Transfer Radical Polymerization Using the Stopped-Flow Technique
Pintauer, Tomislav,Braunecker, Wade,Collange, Edmond,Poli, Rinaldo,Matyjaszewski, Krzysztof
, p. 2679 - 2682 (2004)
The use of stopped-flow techniques to measure activation rate constants for model systems in copper-mediated atom transfer radical polymerization (ATRP) was studied. The structures of model alkyl halides and complexing ligands used in conjunction with CuB
Light-active azaphenalene alkoxyamines: Fast and efficient mediators of a photo-induced persistent radical effect
Bottle, Steven E.,Clement, Jean-Louis,Fleige, Mirco,Simpson, Emily M.,Guillaneuf, Yohann,Fairfull-Smith, Kathryn E.,Gigmes, Didier,Blinco, James P.

Here we report the first example of an alkoxyamine derived from an azaphenalene nitroxide, which when exposed to UV-light, readily undergoes homolysis to efficiently and cleanly re-form a nitroxide. This process selectively cleaves the C-O bond of the alkoxyamine and occurs orders of magnitude more rapidly than any other alkoxyamine homolysis previously described in the literature. We demonstrate the use of light to generate a persistent radical effect (PRE) and apply this to undertake radical insertion, radical exchange and proof of concept polymerization reactions.
Alkyl group dissociation during corona excitation of alkylbenzenes
Yoon, Young Wook,Lee, Sang Kuk
experimental part, p. 741 - 745 (2012/01/03)
Well-resolved vibronic emission spectra were recorded in the visible region from the corona discharge of precursor alkylbenzenes in a technique of corona excited supersonic expansion using a pinhole-type glass nozzle. From the observed spectra, we found t
Understanding atom transfer radical polymerization: Effect of ligand and initiator structures on the equilibrium constants
Tang, Wei,Kwak, Yungwan,Braunecker, Wade,Tsarevsky, Nicolay V.,Coote, Michelle L.,Matyjaszewski, Krzysztof
scheme or table, p. 10702 - 10713 (2009/02/05)
Equilibrium constants in Cu-based atom transfer radical polymerization (ATRP) were determined for a wide range of ligands and initiators in acetonitrile at 22°C. The ATRP equilibrium constants obtained vary over 7 orders of magnitude and strongly depend o
