Chemical Properties

clear colorless to light yellow liquid

Uses

cis-3-Hexene is used as an organic chemical synthesis intermediate.

Definition

ChEBI: Cis-3-hexene is a 3-hexene in which the double bond adopts a cis-configuration. In this compound, there are two hydrogen atoms on one side and two ethyl groups on the other side of the double bond. The structures of cis-3-hexene and trans-3-hexene in gas phase were determined using electron diffraction and molecular mechanical calculations.

General Description

cis-3-Hexene is a symmetrical cis-disubstituted alkene that can be prepared by the hydroboration of 3-hexyne followed by protonolysis. The gas-phase study of its molecular structure by electron diffraction combined with molecular mechanical calculations reveals the presence of the (+ac, +ac) and the (-ac, +ac) forms. cis-3-Hexene undergoes epoxidation with dimethyldioxirane to form the corresponding epoxide.
