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 ...
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 .
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 .
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 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 ...
In organic chemistry, the acenes or polyacenes are a class of organic compounds and polycyclic aromatic hydrocarbons made up of benzene (C 6 H 6) rings which have been linearly fused. [ 1 ] [ 2 ] They follow the general molecular formula C 4 n +2 H 2 n +4 .
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
