| TRANS-2-PENTENE Usage And Synthesis |
| Chemical Properties | colourless liquid |
| Uses | 2-Pentene (mixture of cis and trans) is used in the synthesis of polycyclopentene by ring-opening metathesis polymerization. |
| General Description | 2-Pentene undergoes addition reaction with phenoxathiin cation radical in acetonitrile solution to form bis(10-phenoxathiiniumyl)alkane adducts. |
| Purification Methods | Reflux the mixture with sodium wire, then fractionally distil it twice through a Fenske (glass helices packing, p 11) column. [Beilstein 1 IV 815.] |
