Tropone or 2,4,6-cycloheptatrien-1-one is an organic compound with some importance in organic chemistry as a non-benzenoid aromatic. [2] The compound consists of a ring of seven carbon atoms with three conjugated alkene groups and a ketone group.
In organic chemistry, benzenoids are a class of organic compounds with at least one benzene ring. These compounds have increased stability due to resonance in the benzene rings. Most aromatic hydrocarbons are benzenoid. Notable counterexamples are cyclooctadecanonaene, azulene and trans-bicalicene. [1] [2]
Aromatic properties have been attributed to non-benzenoid compounds such as tropone. Aromatic properties are tested to the limit in a class of compounds called cyclophanes. A special case of aromaticity is found in homoaromaticity where conjugation is interrupted by a single sp³ hybridized carbon atom.
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 ...
Benzaldehyde, organic compound consisting of a benzene ring with a formyl substituent Tropone , or 2,4,6-cycloheptatrien-1-one, a non-benzenoid aromatic Index of chemical compounds with the same molecular formula
This is the general formula for non-benzenoid quinones, in which either m or n can be 0 but not both, and they are both positive integers. In organic chemistry, quinoids are a class of chemical compounds that are derived from quinone. Unlike benzenoid structures, the quinoid part is not aromatic. [1]
Hinokitiol is the first non-benzenoid aromatic compound identified. [8] The compound has a heptagonal molecular structure and was first synthesized by Ralph Raphael in 1951. [ 9 ] Due to its iron-chelating activity, hinokitiol has been called an "Iron Man molecule" in the scientific media, which is ironic because Tetsuo is translated into ...
