13dichloroholene

13-Dichlorholene is a synthetic compound with the chemical formula C4H2Cl2 with two chlorine atoms and a triple bond between the carbon atoms. It is a member of the holene series, which is a class of highly unsaturated aromatic hydrocarbons. The compound features a planar, highly conjugated system of carbon-carbon bonds and carbon-halogen bonds.

13-Dichlorholene is a relatively stable compound, although it may be prone to air oxidation and decomposition over time. It exhibits limited solubility in typical organic solvents due to its hydrophobic nature and planar structure. In some solvents, it may form crystalline needles that can be isolated by recrystallization.

Studies have shown that 13-Dichlorholene is a potent π-electron acceptor and can interact with other molecules through intermolecular interactions. The compound has been investigated for its spectroscopic properties, including ultraviolet (UV) and infrared (IR) absorption. The UV spectrum of 13-Dichlorholene is characterized by a strong absorption band in the near-UV region (∼320-420 nm).

Research has also explored the potential use of 13-Dichlorholene as a model compound for understanding various chemical and physical phenomena. It has been used to investigate electronic properties, reactivity, and solvent effects on the chemical behavior of holene compounds.

13-Dichlorholene and related holene compounds are generally derived from pyrolysis of aromatic anhydrides, such as those found in pyroligneous acid. The purification and storage of these compounds require careful attention to minimize degradation and contamination. Overall, 13-Dichlorholene and other holene compounds present unique chemical and physical properties that warrant continued investigation and analysis.
