The rate of coupling of alkyl radicals with the persistent aminoxyl radical 1,1,3,3-tetramethylisoindolin-N-oxyl (1) has been used as a kinetic probe to determine absolute rate coefficients for the addition of alkyl radicals to methyl acrylate. The results are discussed in terms of the role of the structure and functionalization of the attacking radical on the rates of addition, particularly as they affect steric, polar, and enthalpic factors. The aminoxyl method is assessed against other methods for determining free radical addition rate coefficients.
烷基自由基与持久性氨氧自由基1,1,3,3 - 四甲基异吲哚啉 - N - 氧基（1）的偶联速率已被用作动力学探针，以确定烷基自由基加成到丙烯酸甲酯的绝对速率系数。根据进攻自由基的结构和功能化对加成速率的作用来讨论结果，特别是它们对空间、极性和焓因素的影响。将氨氧自由基方法与其他测定自由基加成速率系数的方法进行了评估。
