For cyclohexane, cyclohexene, and cyclohexadiene, dehydrogenation is the conceptually simplest pathway for aromatization. The activation barrier decreases with the degree of unsaturation. Thus, cyclohexadienes are especially prone to aromatization. Formally, dehydrogenation is a redox process. Dehydrogenative aromatization is the reverse of ...
1,4-Cyclohexadiene is an organic compound with the formula C 6 H 8. It is a colourless, flammable liquid that is of academic interest as a prototype of a large class of related compounds called terpenoids , an example being γ- terpinene .
4,5-Dichloro-3,6-dioxo-1,4-cyclohexadiene-1,2-dicarbonitrile; ... The substance did not receive interest until its potential as a dehydrogenation agent was discovered ...
Two hydrocarbons that can serve as hydrogen donors are cyclohexene or cyclohexadiene. In this case, an alkane is formed, along with a benzene. The gain of aromatic stabilization energy when the benzene is formed is the driving force of the reaction. Pd can be used as a catalyst and a temperature of 100 °C is employed.
Cyclohexadiene and its derivatives form (diene)iron tricarbonyl complexes. Illustrative is [(C 6 H 8)Fe(CO) 3], an orange liquid. This complex reacts with hydride-abstracting reagents to give the cyclohexadienyl derivative [(C 6 H 7)Fe(CO) 3] +. [6] Cyclohexadienes react with ruthenium trichloride to give (Benzene)ruthenium dichloride dimer. [7]
These hydrogen donors undergo dehydrogenation to, respectively, carbon dioxide, acetone, and anthracene. ... The product of this step is a cyclohexadiene, which ...
In chemistry, dehydrogenation is a chemical reaction that involves the removal of hydrogen, usually from an organic molecule. It is the reverse of hydrogenation . Dehydrogenation is important, both as a useful reaction and a serious problem.
