抄録

A series of 7,7-dicyano-8,8-diaryl-p-quinodimethane are readily prepared by the reaction of 4-lithiophenyldicyanomethyllithium with diaryl ketones; the 8-(4-dimethylaminophenyl) compounds thus obtained show solvent-dependent absorption spectra and bond rotation of the exocyclic double bonds and form a head-to-tail dimeric structure in the crystal.
