The reaction course of biradicals, OC↑-(CH2)n−2-C↑Ph2, generated from Norrish type I reaction of 2,2-diphenylcycloalakanones with various ring sizes, is switched from intramolecular disproportionation (n=6,7) to acyl-phenyl recombination (n>-9) in methanol.
由不同环尺寸的2,2-二苯基环芳烷酮的Norrish I型反应产生的双自由基OC ↑ -(CH 2)n−2 -C ↑ Ph 2的反应过程从分子内歧化转换(n = 6 ,7)在甲醇中进行酰基-苯基重组(n> -9)。
