✦ Synopsis

Thermal addition of o-benzoquinones to barrelenes cycloaddition of the face-to-face double bonds. Theoretical methods (semiempirical as well as density functional) were (bicyclo[2.2.2]octatrienes) produces tetracyclic trienediones of type 1. These multichromophoric molecules offer a also used to investigate the spin multiplicity diversity of these reactions. The diketone 7 (bicyclo[2.2.2]octa-5,7-diene-2,3-plethora of photochemical reactions of which the most interesting are (1) rearrangement and bisdecarbonylation of dione) was investigated using He(I) photoelectron spectroscopy. the enedione chromophore and (2) [2π + 2π] intramolecular
