Cyclohexa-1,3-diene is an organic compound with the formula (C 2 H 4)(CH) 4. It is a colorless, flammable liquid. Its refractive index is 1.475 (20 °C, D). It is one of two isomers of cyclohexadiene, the other being 1,4-cyclohexadiene.
1,2,3-Cyclohexatriene is an unstable chemical compound with the molecular formula C 6 H 6. [1] It is an unusual isomer of benzene in which the three double bonds are cumulated . This highly strained compound was first prepared in 1990, by reacting a cyclohexadiene derivative with cesium fluoride . [ 2 ]

cis-1,2-Dihydrocatechol is the organic compound with the formula C 6 H 6 (OH) 2. Several isomers exist with this formula. It is a colorless solid melting near room temperature. The compound is classified as a 1,3-cyclohexadiene. It arises by the dihydroxylation of benzene catalyzed by toluene dioxygenase.
Hyperconjugation affects several properties. [6] [10]Bond length: Hyperconjugation is suggested as a key factor in shortening of sigma bonds (σ bonds). For example, the single C–C bonds in 1,3-butadiene and propyne are approximately 1.46 Å in length, much less than the value of around 1.54 Å found in saturated hydrocarbons.
The Cope rearrangement is an extensively studied organic reaction involving the [3,3] sigmatropic rearrangement of 1,5-dienes. [14] [15] [16] It was developed by Arthur C. Cope. For example, 3,4-dimethyl-1,5-hexadiene heated to 300 °C yields 2,6-octadiene. The Cope rearrangement of 3,4-dimethyl-1,5-hexadiene

2 RuCl 3 ·xH 2 O + 7 PPh 3 → 2 RuCl 2 (PPh 3) 3 + OPPh 3 + 5 H 2 O + 2 HCl. Diruthenium tetraacetate chloride, a mixed valence polymer, is obtained by reduction of ruthenium trichloride in acetic acid. [RuCl 2 (C 6 H 6)] 2 arises from 1,3-cyclohexadiene or 1,4-cyclohexadiene as follows: [13] [14] 2 RuCl 3 ·xH 2 O + 2 C 6 H 8 → [RuCl 2 (C ...
