TRANS-1,3-PENTADIENE Structural

What is TRANS-1,3-PENTADIENE?

Definition

ChEBI: An alkadiene consisting of pentane with the two double bonds located at positions 1 and 3.

General Description

Trans-1,3-Pentadiene spectra is recorded in the 5000-17500 cm(-1) region with conventional and intracavity laser photoacoustic spectroscopy. It can be determined by the spectrophotometric method based on the Diels-Alder reaction. In this reaction, cisoid 1,3-dienes and tetracyanoethylene (TCNE) react with an aromatic-TCNE pi-complex.

Safety Profile

Poison by intravenous route. A very dangerous fire and explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Distil the diene from NaBH4. Purify it also by preparative gas chromatography. [Reimann et al. J Am Chem Soc 108 5527 1986, Beilstein 1 IV 994.]
