A mixture of four dimers (8X) is obtained from the benzophenone-sensitized irradiation of the triene (164). Vacuum sublimation of this mixture affords the dimer (165) which was subsequently converted by conventional chemical paths to the hydrocarbon (166).Photosensitized (Rose Bengal) dimerization of aceanthrylene (167) has been studied in methanol solution. This affords both the syn- and anti-head-to-head and head-to-tail stereoisomers. The results indicate that there is a slight preference for the formation of the syn-adduc t s. ... 

The higher homologs of acenaphthylene dianion 82 are the aceanthrylene dianion 33 and acephenanthrylene dianion 34 122,123). The convenient synthesis of the the hydrocarbon enabled a detailed investigation of their metal reduction and the exploration of their patterns of delocalization. Despite their being (4n + 2)ji-electron systems, these anions are not diatropic as one may expect from counting their jc-electrons.
