Hazard Information | Back Directory | [Chemical Properties]
colourless liquid | [Uses]
Forms benzene at elevated temperatures in the presence of a ruthenium(II)-triphenylphosphine catalyst.1 | [Uses]
Reagent for selectively cleaving benzyl esters in the presence of benzyl ethers by catalytic H-transfer. | [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.] |
