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.]
