Sensitized photo-oxygenation of a wide variety of acyclic 1,3-dienes was investigated. The 1,4-cycloaddition of singlet oxygen to acyclic conjugated dienes was closely related to the thermal Diels-Alder reaction in stereospecificity, and steric and electronic effects of substituents. Reactivity order of singlet oxygen toward conjugated dienes and isolated C—C double bonds was exhibited as follows:
研究了多种无环1,3-二烯的敏化光氧合。单线态氧在无环共轭二烯上的1,4-环加成反应与立体特异性的热Diels-Alder反应以及取代基的空间和电子效应密切相关。单线态氧对共轭二烯和分离的CC双键的反应顺序如下:三取代单烯烃> 2-取代的1,3-二烯>二取代单烯烃。
