The heterolysis of 1-adamantyl iodide in acetonitrile was studied preparatively and kinetically (in the presence of triphenylverdazyl as internal indicator).Additions of LiClO4, Et4N+ClO4-, Et4N+OTs-, Et4N+I-, and Et4N+Br- do not affect the reaction rate; the normal salt effect and the salt effect of the law of mass action do not appear.Additions of water increase the reaction rate a little, while additions of LiBr, Bu4N+NO3-, LiCl, and Et4N+Cl- reduce it greatly.It is suggested that an intimate ion pair of the substrate is converted into a solvent- separated ion pair in the controlling stage of the reaction.
