Cyclohexa-1,4-diene Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Uses

Reagent for selectively cleaving benzyl esters in the presence of benzyl ethers by catalytic H-transfer.

Uses

Forms benzene at elevated temperatures in the presence of a ruthenium(II)-triphenylphosphine catalyst.1

Uses

1,4-Cyclohexadiene is used to study the formation of parent ion from heavy fragmentation on irradiation with a high-intensity laser pulse. It is also used as a very effective hydrogen donor for catalytic hydrogenation reaction. It forms benzene at elevated temperatures in the presence of a ruthenium(II)-triphenylphosphine catalyst.

Definition

ChEBI: Cyclohexa-1,4-diene is a cyclohexadiene.

General Description

1,4-Cyclohexadiene is an effective hydrogen donor for catalytic hydrogenation reactions. It can rapidly replace benzyl groups of N-benzyloxycarbamates, benzyl esters, benzyl ethers and benzyl amines with hydrogen. It forms benzene at elevated temperatures in the presence of a ruthenium(II)-triphenylphosphine catalyst.

Purification Methods

Dry the diene over CaCl2 and distil it in a vacuum under N2. [Hückel & W.rffel Chem Ber 88 338 1955, Giovannini & Wegmüller Helv Chim Acta 42 1142 1959.] [Beilstein 5 IV 385.]
