摘要:

研究了六苯基苯衍生物的分子内光化学关环脱氢反应,与热化学关环脱氢反应不同,光化学关环脱氢反应只生成关一个环的产物。光化学关环脱氢反应过程中,氧化剂种类、用量以及溶剂对关环脱氢产物的产率具有显著影响,在正己烷溶剂中,以单质碘为氧化剂进行光化学关环脱氢反应,关环产物产率可达91%。

Abstract:

Intramolecuar photocyclodehydrogenation of hexa(4-substituted-phenyl)benzene was studied. The photocyclodehydrogenation reaction gives the only product with one bond formation, which is different from the steady state cyclodehydrogenation reaction. The yield of photocyclodehydrogenation product was affected by the amount and the type of oxidants, and solvents. The yield of 91% has been achieved in n-hexane by using iodine as the oxidant.

Key words: hexa(4-substituted-phenyl)benzene, photocyclodehydrogenation reaction, oxidation
