Studies on the Thiophene Compounds. III. Effects of Substituents on the Dissociation Constants of Thiophenecarboxylic and Thiopheneacetic Acid
この論文をさがす
説明
Acid dissociation constants of substituted thiophenecarboxylic acids and thiopheneacetic acids were determined, and it was shown that the Hammett's law can be applied to thiophene ring even if the effect of the first substituent is considered apparently to be transported to the second substituent merely through the carbon chain of thiophene ring. From these rho-values, combined with what are already known of furan and benzenecarboxylic acid, it was attempted to explain the effects of hetero atoms in the five membered heteroatomatic rings from the stand point of electronegativity and polarisability.
