• General Description: 4-METHYL-1-CYCLOHEXENE (also known as 4-Methylcyclohexene or NSC 9386) is a cyclohexene derivative with a methyl group at the 4-position. The study suggests that its complexation stability with silver ions is influenced by steric and electronic factors, though it generally exhibits lower affinity compared to cyclopentenes due to the ring size effect. The presence of the methyl substituent may reduce complex stability relative to unsubstituted or differently substituted cyclohexenes, as steric hindrance near the double bond can weaken interactions with silver ions. However, specific stability constants for 4-methyl-1-cyclohexene are not explicitly detailed in the provided abstract.

DETERMINATION OF THE STABILITY CONSTANTS OF COMPLEXES BY GAS CHROMATOGRAPHY

10.1021/j100812a519

The study investigates the stability constants of olefin-silver ion complexes in ethylene glycol solutions using gas chromatography. Olefins coordinate with silver ions to form complexes, and the stability of these complexes is influenced by factors such as the position and size of substituents on the olefins. For instance, a methyl substituent at the double bond reduces complex stability due to steric effects, while electronic factors play a role in the higher complex formation tendency of certain 3-alkylcyclopentenes compared to 4-alkyl isomers. The study also finds that cyclopentenes have a higher affinity for silver ions than corresponding cyclohexenes. The stability constants for various olefins, including 1-methylcyclohexene, 3-methylcyclohexene, 4-methylcyclohexene, methylenecyclohexane, and others, are determined and compared, providing insights into the effects of molecular structure on complex stability.
