The results of the first systematic study of the effect of isotopic substitution on the rates of electron transfer for reactions in the inverted region are reported. Rates of return electron transfer within germinate radical ion pairs of 9,10-dicyanoanthracene (DCA) and 2,6,9,10-tetracyanoanthracene (TCA) radical ions and radical cations of perdeuteriated methyl-substituted benzene derivatives determined
报告了同位素取代对反相区域反应电子转移速率影响的首次系统研究的结果。9,10-二氰基蒽 (DCA) 和 2,6,9,10-四氰基蒽 (TCA) 自由基离子和全氘化甲基取代苯衍生物的自由基阳离子的萌发自由基离子对内的返回电子转移速率由先前报道的方法测定被列出。计算了两组离子对的电子转移反应的自由能,在每种情况下,氘代阳离子的反应都比未氘代自由基阳离子的反应慢。图 1,2 个标签。
