Infrared spectrum of 2-hydroxyphenyl, C6H4-OH, produced from 2-iodophenol in a low-temperature argon matrix upon UV irradiation (λ>280 nm) was measured with an FT-IR spectrophotometer. This radical was found to be less stable by 120 kJ mol−1 than phenoxyl, C6H5-O, by a density functional theory calculation. Two final photoproducts were identified as cyclopentadienylidenemethanone and 4-iodo-2,5-cyclohexadienone
2-羟苯基的红外光谱 用FT-IR分光光度计测量由2-碘苯酚在低温氩气基质中于紫外线照射(λ > 280 nm)时产生的C 6 H 4 -OH 。发现该自由基比苯氧基C 6 H 5 -O不稳定120 kJ mol -1,通过密度泛函理论计算。与2-氯和2-溴苯酚的光产物类似,鉴定出两个最终的光产物为环戊二烯亚甲基甲酮和4-碘-2,5-环己二酮。动力学分析表明,后者是通过2-羟苯基通过氢迁移和碘重组产生的,而前者是通过消除碘化氢后的Wolff重排而产生的。
