Abstract

The role of seven hydroxylic solvents $(C_6H_5CH_2OH_, \ CH_3OH, \ C_3H_7OH, \ _i_C_3H_7OH, CH_3OCH_2CH_2OH, \ C_2H_5OCH_2CH_2OH)$ on the rates of the reactions in which heterocyclic amines (pyridine,3-methylpyridine, 3,4-dimethylpyridine) are either the leaving or entering group in process of the type $A_uCl_3(_a_m)+Y-and A_uCl_4-+$ am have been studied. The results indicate that the sequence of solvent effect upon the second-order rate constants is unaffected by the nature of the amine but is quantitatively reversed on going from the reactions of $ A_uCl_4-$ with amines to those of the neutral $A-uCl_3(_a_m)$with chloride and, to a smaller extent, bromide anion. This is discussed in terms of relative solvation of the charged species in the ground and transition states.
