Trypticene
Triptycene is an aromatic hydrocarbon, the simplest iptycene molecule with the formula C2H2(C6H4)3. It is a white solid that is soluble in organic solvents. The compound has a paddle-wheel configuration with D3h Symmetry group, symmetry. It is named after the medieval three-piece art panel, the triptych. Several substituted triptycenes are known. Barrelenes are structurally related. Due to the rigid framework and three-dimensional geometry, derivatives of triptycene have been well researched. Synthesis The parent triptycene was first prepared in 1942 by a multistep method. It can also be prepared in one step in 28% yield from the Diels–Alder reaction of anthracene and benzyne. In this method, benzyne is generated by the reaction of magnesium and 2-bromofluorobenzene. Derivatives and applications The hydrocarbon framework is very rigid and triptycene derivatives such as triptycene quinones are therefore incorporated in many organic compounds as a molecular scaffold for vario ...

Aromatic Hydrocarbon
Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The parent member of aromatic compounds is benzene. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. The current definition of aromatic compounds does not have any relation with their smell. Heteroarenes are closely related, since at least one carbon atom of CH group is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. 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 nitrogen atom. Hydrocarbons without an aromatic ring are called aliphatic. Benzene ring model Benzene, C6H6, is the least complex aromatic hydrocarbon, and it was the first one named as such ...
