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.
Useful for the reduction of radical intermediates formed in electron-transfer mediated ring-opening reactions

We report the first study of UV-induced photoisomerization probed via core ionization by an x-ray laser. We investigated x-ray ionization and fragmentation of the cyclohexadiene-hexatriene system at 850 eV during the ring opening. We find that the ion-fragmentation patterns evolve

Relatively little is known about structural transformations of very small metal clusters that result from the adsorption of molecules. Here, the ligand-induced structural transformation of Ag(5)(+)(g) by 1,4-cyclohexadiene, which is capable of binding metal clusters as a bidentate ligand, is
