General description

1,4-Cyclohexadiene is an effective hydrogen donor for catalytic hydrogenation reaction. The interaction between graphene segments and 1,4-cyclohexadiene was stuided using density-functional tight-binding (DFTB) method.

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.

A cyclohexadiene ligand prepared by microbial arene 1,2-dihydroxylation undergoes spontaneous rearrangement upon complexation to tricarbonyliron(0). Subsequent iron removal affords a novel route to formal arene 2,3-dihydroxylation products enantiomeric to those obtainable by direct microbial arene oxidation.

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

DFT calculated barriers for C-H activation of 1,4-cyclohexadiene by nonheme iron(IV)-oxo and iron(III)-superoxo species show that the experimental trends can be explained if the spin inversion probability of the TMC iron(IV)-oxo is assumed to be poor. Also, the TMC iron(III)-superoxo
