YELLOW NEEDLES | [Uses]
Biphenylene can be used as an intermediate in pharmaceutical synthesis.
| [Definition]
ChEBI: Biphenylene is an ortho-fused polycyclic arene and an ortho-fused tricyclic hydrocarbon. | [Synthesis]
Biphenylene is obtained by several methods; one of the best, in spite of the low yield, involved pyrolysis of dibenziodolium iodide in the presence of cuprous oxide.
| [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.] |
