laser flash photolysis (LFP) studies to generate alkoxyl radicals that fragmented to give the (2,2-diphenylcyclopropyl)methyl radical. Rate constants for the beta-scission reactions increased as a function of the carbonyl compound produced in the fragmentation reaction in the order CH2O < MeCHO < Me2CO < PhCHO < Ph2CO and increased with increasing solvent polarity. For alkoxyl radicals that fragment
在激光闪光光解(LFP)研究中使用了一系列对硝基苯磺酸酯,以生成烷氧基基团,这些基团碎裂后得到(2,2-二苯基环丙基)甲基基团。β断裂反应的速率常数随裂解反应中生成的羰基化合物的增加而增加,顺序为CH2O
