    环状硝基氧基片段的立体和极性效应对C-ON键均解速率常数的影响
    摘要:
    烷氧基胺和持久性硝氧基自由基是氮氧化物介导的自由基聚合(NMP)的重要调节剂。因为聚合时间随着聚合物链和硝酰基部分之间C-ON键均化的速率常数的增加而减少,所以影响裂解速率常数的因素引起了人们的极大兴趣。在这里,我们介绍在新的环烷氧基胺模型中C-ON键断裂的速率常数(k d)的测量。的9个新烷氧基胺和33个他人通过文献中给出的均裂速率常数分析与关于极性感应/场(σ的贡献我)效应,空间(Ë小号)效应和硝酰基部分的分子内氢键(IHB)的效果,使用由商品型号建立的多参数方程,即日志(ķ d / ķ d,0)=-3.07σ我- 0.88 ë小号- 5.88。建立了七元环和八元环的循环空间常数r(R i)。结果的分析为烷氧基胺构象对k d值的重要性提供了新的见解。

    are of considerable interest, but up to now, the polar/stabilization effects have not been addressed thoroughly. The combination of new data with previously reported data now showed that the re-formation rate constant kc increases with the increasing polar character of the substituents attached to the nitroxide moiety. The polar/stabilization effects are weaker for the re-formation than for the homolysis
