Abstract
By the reaction of selenopyrylium salts with phenyllithium, two selenabenzene analogs, namely, 10-phenyl- and 9, 10-diphenyl-10-selenaanthracenes have been prepared. The selenaanthracene derivatives are very stable against light, heat, and oxygen. The nuclear magnetic resonance and mass spectral data and the low dipole moment (1.08 D) strongly suggest a covalent aromatic structure for the selenaanthracene.
