The C 4-benzenes are a class of organic aromatic compounds which contain a benzene ring and four other carbon atoms. There are three tetramethylbenzenes , six dimethylethylbenzenes, three diethylbenzenes , three isopropylmethylbenzenes , three n -propylmethylbenzenes and four butylbenzenes .
Benzene is an organic chemical compound with the molecular formula C 6 H 6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
The symmetrical molecule [3.3]orthocyclophane, also known as janusene, is a cyclophane that contains 4 benzene rings in a cleft-shaped arrangement. First synthesized in 1967 by Stanley J. Cristol through the cycloaddition of anthracene and dibenzobarrelene, [ 22 ] the molecule has been used to study stacking and interactions between cations and ...
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
Many simple aromatic rings have trivial names. They are usually found as substructures of more complex molecules ("substituted aromatics"). Typical simple aromatic compounds are benzene, indole, and pyridine. [1] [2] Simple aromatic rings can be heterocyclic if they contain non-carbon ring atoms, for example, oxygen, nitrogen, or sulfur.
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .
The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH 3) as a substituent. [1] Through their different arrangement, they form three structural isomers with the molecular formula C 10 H 14. They also belong to the group of C 4-benzenes.
A cycloparaphenylene is a molecule that consists of several benzene rings connected by covalent bonds in the para positions to form a hoop- or necklace-like structure. Its chemical formula is [C 6 H 4] n or C 6n H 4n Such a molecule is usually denoted [n]CPP where n is the number of benzene rings. An "armchair" carbon nanotube and a ...
