With two O, S or NR groups and two CCdouble bondsin a ring, the systems are not aromatic, and there is no reason to expect them to be planar. In fact, the simple systems are little known, and, except for 1,4-dithiin, it is necessary to look for data from fairly heavily substit...

On the basis of the above comparison tests (Table1), and given that traditional hydroprocessing with exogenous hydrogen source resulted not only in the unavoidable hydrogenation of the benzene ring to cyclohexane but also in the n-propylbenzene byproduct that could not be further converted into ben...
Because of the effect of electronic withdrawing group, hydrogenation activity decreases with increasing alkyl group number in benzene ring with the order of benzene > toluene > xylene > TMB > TeMB [6]. Hydrogenation reactions are also known being sensitive to the acidity of zeolite [7, 8]. A...
Benzene is a clear, volatile, colorless, highly flammable liquid with a pleasant, characteristic odor. It is an aromatic hydrocarbon that boils at 80.1 DC. Benzene is used as a solvent in many areas of industries, such as rubber and shoe manufacturing, and in the production of other important...
Tert-Amylbenzene, with the chemical formula C11H16, has the CAS number 2049-95-8. It is a colorless liquid with a sweet, fruity odor. The basic structure of tert-Amylbenzene consists of a benzene ring attached to a tert-amyl group. This compound is insoluble in water, but it is so...
1,4-Difluorobenzene, with the chemical formula C6H4F2, has the CAS number 540-36-3. It appears as a colorless liquid with a faint, sweet odor. The basic structure of 1,4-Difluorobenzene consists of a benzene ring with two fluorine atoms attached to the 1 and 4 positions. This compou...
The conjugated six-membered ring is also the building block of graphene6, a material with astonishing electronic properties. Benzene is the archetypal aromatic molecule, displaying exceptional chemical stability as compared with other unsaturated hydrocarbons. It was first reported in 1825 by Faraday7, ...
It has a basic structure consisting of a benzene ring with two methyl groups attached to it, and a thiol group (-SH) attached to one of the carbon atoms in the benzene ring. This compound is soluble in organic solvents such as ethanol and ether, but has limited solubility in water. It...
The intermediates IM1A and IM1B can generate the epoxide intermediates IM2A and IM2B via a ring-closure step with transition state TS2. The epoxide intermediates have the lowest energy and − 15.5 and − 21.8 kcal mol− 1 below IM2B are very similar showing Fe1N and Fe2N distances ...
