Abstract

Rate constants k(d) of the C-ON bond homolysis in a new type of alkoxyamines (initiator/controller for Nitroxide Mediated Polymerization) carrying alkyl fragments capable of protonation were measured. A 20-fold increase was reported for the protonated alkoxyamine compared to the non-protonated homologue as predicted (Chem. Soc. Rev., 2011).

摘要

测量了带有可质子化烷基片段的新型烷氧基胺（用于氮氧自由基聚合的引发剂/控制器）中 C-ON 键均裂的速率常数 k(d)。正如所预测的那样，与非质子化的同系物相比，质子化的烷氧基胺的速率常数增加了 20 倍（Chem. Soc. Rev.，2011）。
