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.
