trans-2-Pentene Usage And Synthesis
Chemical Propertiescolourless liquid
Uses2-Pentene (mixture of cis and trans) is used in the synthesis of polycyclopentene by ring-opening metathesis polymerization.
General Description2-Pentene undergoes addition reaction with phenoxathiin cation radical in acetonitrile solution to form bis(10-phenoxathiiniumyl)alkane adducts.
Purification MethodsReflux the mixture with sodium wire, then fractionally distil it twice through a Fenske (glass helices packing, p 11) column. [Beilstein 1 IV 815.]
