摘要: 近年来芳烃和杂环化合物的电子转移光氧化反应受到日益的注意[1-5]。电子转移光氧化反应不仅可应用于很多对1O2为惰性的烯烃和芳烃[1-7],而且对某些1O2活性化合物,也可给出与1O2反应不同的产物。

Abstract: The 9,10-dicyanoanthracene (DCA) and chloranil (TCBQ) sensitized electron transfer photooxygenations of α-methoxy-naphthalene (α-MN) were studied.In both cases a complex mixture of products was obtained,of which the isolable components were 1,4-naphthoquinone and 4-methoxy-1,2-naphthoquinone.The reaction mechanism was discussed.In DCA sensetized reaction,superoxide ion O2- and 3O2 were the species responsible for the oxygenation while the TCBQ sensitized reaction was a radical oxidation reaction involving 3O2.Ground state charge transfer complex formation between TCBQ and α-MN was investigated.

Key words: Photooxygenation, electron transfer, a-methoxy-naphthalene
