  激光闪光光解法研究溶液中将2-羟基-2-丙基自由基加成烯烃的速率常数

  摘要：

  在室温下，已确定了在MeOH中将高度亲核性的2-羟基-2-丙基自由基加到8个快速反应的1-和1,1-二取代的烯烃中的绝对速率常数，方法是通过激光闪光光解法确定的。还给出了2-羟基-2-丙基以及苄基和烷基型加合物基团的吸收光谱。速率常数是使用各种方法分析动力学痕迹并支持较早的发现而获得的。

  In this study, we present a new aprotic solvent, 2,4-dimethoxy-2,4-dimethylpentan-3-one (DMDMP), which is designed to resist nucleophilic attack and hydrogen abstraction by reduced oxygen species. Li–O2 cells using DMDMP solutions were successfully cycled. By various analytical measurements, we showed that even after prolonged cycling only a negligible amount of DMDMP was degraded. We suggest that

  在这项研究中，我们提出了一种新的非质子传递溶剂，2,4-二甲氧基-2,4-二甲基戊烷-3-酮（DMDMP），其设计用于抵抗亲核攻击和减少的氧物种引起的氢提取。使用DMDMP溶液的Li–O 2电池已成功循环。通过各种分析测量，我们表明，即使延长了循环时间，DMDMP的降解量也可忽略不计。我们建议，观察到的基于Li–O 2 DMDMP的电池容量下降是由于循环过程中锂阳极的不稳定性所致。对氧气种类的稳定性使DMDMP成为许多涉及氧气还原和各种评估反应的电化学系统的极佳候选溶剂。
