WebSep 29, 2024 · Pyrolysis and/or metal-catalyzed dimerization of biphenylenes. Despite the fact that benzyne (4) might be too reactive for tetramerization by cyclization to provide tetraphenylenes, biphenylene (5) can be viewed as a dimer of o-benzyne.Pyrolysis of 5 in liquid phase at a high temperature of 400°C afforded an essentially quantitative yield … Polycycles containing the biphenylene nucleus have also been prepared, some having considerable antiaromatic character. In general, additional 6-membered rings add further aromatic character, and additional 4-membered and 8-membered rings add antiaromatic character.
