Synthesis and Properties of 1,5-Dimethyltricyclo2,8>octane- and 1,5-Dimethyltetracyclo2,804,6>octane Derivatives

The synthesis of 1,5-dimethyltricyclo2,8>octane-3,7-dione (2), 1,5-dimethyltetracyclo2,804,6>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 ? frame in 2 and 3 as well as of the double bonds in 5 and 6 and the ? frame is found.These interactions are also traced back by the electronic absorption spectra of these compounds.The molecular structures of 2 and 3 have been investigated by X-ray analysis.
