Abstract

Abstract: The synthesis and properties of the “antiaromatic” hydrocarbon dicycloocta [1, 2, 3, 4-def: 1', 2', 3', 4'-jkl] biphenylene (1) are described. The observed electronic and 'H NMR spectra of 1 agree well with previous predictions. The series of polycycles consisting of biphenylene (3), cycloocta [defl biphenylene (Z), and dicycloocta [dejjkl] biphenylene (1) is examined in terms of resonance energy and qualitative aromaticity models.
