摘要/Abstract

摘要： 本文报道蒈烯在不同溶剂中光敏氧化反应产物的组成和分布及其与溶剂及敏化剂性质的关系。研究结果指出在以孟加拉玖瑰红(RB)为敏化剂时,主要生成典型的“ene”型产物,而以9,10—二腈基蒽敏化蒈烯的光氧化反应除生成“ene”型产物外还生成相当量的非“ene”型产物。实验证明蒈烯芳氰敏化光氧化反应过程,首先发生电子转移,而后产生自由基中间体和单重态氧并生成相应产物。

关键词: 蒈烯, 9,10一二腈基蒽(DCA), 孟加拉玖瑰红(RB), 电子转移、单重态氧

Abstract: This paper reported that the product distribution of photosensitized oxygenation of carene by aromatic cyanide are related to solvent and sensitizers.The experimental results indicated that the products formed with rose bengal as sensitizer are typical " ene " type products and non- " ene " type product increase more than 30%, except " ene " type products in the presence of DCA as sensitizer.The investigation result shows that DCA sensitized photooxygation of carene include both electron and energy transfer process.

Key words: carene, 9,10-dicyanoanthracene (DCA), rose bengal (RB), electron transfer
