The photochemical behavior of differently substituted N‐arylsulfonimides was investigated. Homolysis of the S−N bond took place as the exclusive path from the singlet state to afford both N‐arylsulfonamides and photo‐Fries adducts, the amount of which depended on reaction conditions and aromatic substituents. Sulfinic and sulfonic acids were released upon irradiation under deaerated and oxygenated
研究了不同取代的N-芳基磺酰亚胺的光化学行为。从单重态到同时提供N-芳基磺酰胺和光爆加合物的过程中,SN键的均相分解是唯一的途径,其数量取决于反应条件和芳族取代基。亚硫酸和磺酸分别在脱气和充氧条件下辐射后释放。通过激光闪光光解和EPR实验证明了所涉及的激发态和中间体的性质。这些结果突出了这类化合物作为非离子型光酸产生剂的潜力,该化合物能够为每摩尔底物光释放多达两当量的强酸。
