135Cyclooctatriene

135cyclooctatriene is a cyclic organic compound with the chemical formula C8H10. It is an isomer of cyclooctadiene and cyclooctyne, featuring a ring of eight carbon atoms with three double bonds. The numbering 1,3,5 indicates the positions of these double bonds within the cyclooctatriene ring.

There are several possible geometric isomers of 1,3,5-cyclooctatriene due to the presence of the double bonds. These isomers differ in the spatial arrangement of atoms around the double bonds, specifically whether they are in the cis or trans configuration. The most common and stable isomer is cis,cis,cis-1,3,5-cyclooctatriene.

1,3,5-Cyclooctatriene is a colorless liquid at room temperature. It is typically prepared through chemical synthesis rather than being found naturally. Its reactivity is characteristic of conjugated trienes, undergoing reactions such as Diels-Alder cycloadditions and electrophilic additions.

Due to its conjugated pi system, 1,3,5-cyclooctatriene exhibits some aromatic character, though it is not considered fully aromatic. This partial aromaticity influences its electronic properties and spectroscopic behavior. It is a subject of study in organic chemistry for understanding conjugation and reaction mechanisms in cyclic systems.
