Cattalini, L. and Ricevuto, Vittorio and Orio, A. A. and Tobe, Martin L. (2005) The effect of Hydroxylic Solvents on the Kinetic Behavior of Gold(III) Complexes. Accademia Peloritana dei Pericolanti Classe FF.MM.NN., 83. pp. 41-47.
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.
