초록

The interactions of iodine with toluidines (o-, m-, and p-) and N-methyltoluidines (o-, m-, and p-) in $CCl_4$ solution have been investigated through spectrophotometric measurements. The results indicate that toluidines and N-methyltoluidines form the one-to-one charge-transfer complexes with $I_2$ in solution. By comparing the values of the formation constants of the complexes, it is concluded that the relative stabilities of the $I_2$-amine complexes decrease in the following orders: p-toluidine >m-toluidine >aniline >o-toluidine, N-methyl-p-toluidine >N-methyl-m-toluidine >N-methylaniline >N-methyl-o-toluidine, N-methyltoluidines >toluidines. These results can be explained by the electron-releasing character and the steric effect of methyl group in the amine molecules.
