Photolysis of benzyl β-naphthyl sulfoxide results mainly in α-cleavage. The isomeric sulfenic ester is the major product. Because the triplet energies of both the sulfoxide and sulfenic ester are below that of acetone, in contrast to the previously studied phenyl and tolyl cases, interpretation of sensitization experiments is straightforward. The sulfinyl radical is characterized by transient absorption
苄基β-萘基亚砜的光解作用主要导致α裂解。异构亚磺酸酯是主要产物。由于亚砜和亚磺酸酯的三重态能量均低于丙酮,因此与先前研究的苯基和甲苯基情况相反,敏化实验的解释很简单。亚硫酰基的特征在于瞬时吸收,并提出了一个模型来说明其与氮氧自由基的反应性。
