reaction of the phenyl radical 1 with water has been investigated by using matrixisolation spectroscopy and quantum chemical calculations. The primary thermal product of the reaction between 1 and water is a weakly bound complex stabilized by an OH⋅⋅⋅π interaction. This complex is photolabile, and visible‐light irradiation (λ>420 nm) results in hydrogen atom transfer from water to radical 1 and the formation

The photolysis of benzene/ozone mixtures in an argon matrix at 12 K with UV light of λ ≥ 280 nm leads to the following products: phenol, 2,4-cyclohexadienone, benzene oxide, and butadienylketene (hexa-1,3,5-trien-1-one). The identification of butadienylketene as a product is based on deuterium isotopic shifts and agreement with density functional vibrational frequency calculations. We find an average
苯/臭氧混合物在 12 K 的氩气基质中使用 λ ≥ 280 nm 的紫外光进行光解产生以下产物:苯酚、2,4-环己二烯酮、苯氧化物和丁二烯基乙烯酮(六-1,3,5-三一一)。丁二烯烯酮作为产品的鉴定是基于氘同位素位移和密度函数振动频率计算的一致性。我们发现在光解过程中苯酚/丁二烯基乙烯酮的平均支化比为 4.3。这是文献中首次报道氧原子与苯反应生成乙烯酮产物。
