The synthesis of 1,5-dimethyltricyclo[3.3.0.02,8]octane-3,7-dione (2), 1,5-dimethyltetracyclo[3.3.0.02,804,6]-octane-3,7-dione (3), the corresponding dienes 5 and 6 as well as the mixed enones 13–15 is reported. Using He(I) photoelectron spectroscopy (PE) as a tool, a considerable interaction between the n orbitals on the O-atoms and the σ frame in 2 and 3 as well as of the double bonds in 5 and 6
1,5-二甲基三环[3.3.0.0 2,8 ]辛烷-3,7-二酮(2),1,5-二甲基四环[3.3.0.0 2,8 0 4,6 ]-辛烷-3,7的合成-二酮(3),相应的二烯烃5和6以及混合烯酮13 - 15进行报告。使用He(I)光电子能谱(PE)作为工具,O原子上的n个轨道与2和3中的σ框架以及5和6中的双键之间有相当大的相互作用并找到σ框架。这些相互作用还可以通过这些化合物的电子吸收光谱来追溯。通过X射线分析研究了2和3的分子结构。
