Description

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.

Application

1,4-Cyclohexadiene (1,4-CHD) was used to study the formation of parent ion from heavy fragmentation of 1,4-CHD on irradiation with a high-intensity laser pulse.

Packaging

5, 25, 100 mL in glass bottle
