Trans12dichlorocyclohexane

Trans-1,2-dichlorocyclohexane is an organic compound with the chemical formula C6H10Cl2. It is a stereoisomer of 1,2-dichlorocyclohexane, specifically the isomer where the two chlorine atoms are positioned on opposite sides of the cyclohexane ring in a trans configuration. This means that if one chlorine atom is in an axial position, the other is in an equatorial position, or vice versa, relative to the ring's conformation. In its most stable chair conformation, both chlorine atoms are typically equatorial to minimize steric strain.

This compound is a colorless liquid or solid, depending on purity and ambient temperature, with a distinct odor. It is relatively insoluble in water but soluble in many organic solvents. Trans-1,2-dichlorocyclohexane can be synthesized through various chemical reactions, often involving the addition of chlorine to cyclohexene. It is a precursor or intermediate in the synthesis of other organic chemicals. Its reactivity is primarily associated with the chlorine atoms, which can undergo nucleophilic substitution or elimination reactions. For example, dehydrohalogenation can lead to the formation of chlorocyclohexene. Due to the presence of chlorine, it is considered an organochlorine compound. Its properties and applications are largely dictated by its stereochemistry and the nature of the carbon-chlorine bonds.
