The ring-substituted 1-naphthylmethyl esters of phenylacetic (3a-k) and 3-phenylpropanoic (5a-c) acid have been photolyzed in methanol solvent. The major products of these reactions are derived from two critical intermediates, the 1-naphthylmethyl radical/acyloxy radical pair and the 1-naphthylmethyl cation/carboxylate anion ion pair. The radical pair results in formation of the in-cage coupled products
苯乙酸 (3a-k) 和 3-苯基丙酸 (5a-c) 酸的环取代 1-萘基甲酯已在甲醇溶剂中光解。这些反应的主要产物来自两个关键中间体,即 1-萘甲基自由基/酰氧基自由基对和 1-萘甲基阳离子/羧酸根阴离子对。在从酰氧基中失去二氧化碳后,自由基对导致形成笼内偶联产物 8a-k 和 10a-c。离子对导致甲基醚 6a-k 和羧酸 7 和 9
