Questions of bond alternation and ring currents have been investigated repeatedly. See more Biphenylene is an organic compound with the formula (C6H4)2. It is a pale, yellowish solid with a hay-like odor. Despite its unusual structure, it behaves like a traditional polycyclic aromatic hydrocarbon. See more Biphenylene was first synthesized by Lothrop in 1941. The biphenylene structure can also be understood as a dimer of the reactive intermediate benzyne, which in fact serves as a major synthetic route, by heating the benzenediazonium-2-carboxylate See more Researchers synthesized a biphenylene sheet consisting of sp2-hybridized carbon atoms that formed four-, six-, and eight-membered rings on a smooth gold surface. A bottom-up two-step interpolymer dehydrofluorination of an adsorbed See more Biphenylene is a polycyclic hydrocarbon, composed of two benzene rings joined by two bridging bonds (as opposed to a normal ring fusion), thus forming a 6-4-6 arene system. The resulting planar structure was one of the first π-electronic hydrocarbon … See more Polycycles containing the biphenylene nucleus have also been prepared, some having considerable antiaromatic character.
