Abstract
Metaxylylene 1 is potentially regarded as a resonance hybrid between a diradical form A and a zwitterionic form B. Although the diradical A has been received much attention mainly from the viewpoints of high-spin organic compounds,1 few studies on the zwitter ion B have been performed so far.2 Recently we have reported the highly polarized character of 7,7-dicyano-8 ,8-bis(4- dimethylaminophenyl)-p-quinodimethane (2).3 The results sug- gest that ...
