| BIPHENYLENE Usage And Synthesis |
Chemical Properties | YELLOW NEEDLES | Definition | ChEBI: Biphenylene is an ortho-fused polycyclic arene and an ortho-fused tricyclic hydrocarbon. | Purification Methods | Biphenylene from yellow crystals from cyclohexane, MeOH (m 110-111o) or EtOH (m 111-112o). It sublimes in vacuo. The 2,4,7-trinitrofluorenone complex has m 154o and the picrate gives red needles m 122o from EtOH. [Beilstein 5 I 298, 5 II 530, 5 III 1935, 5 IV 2137.] |
