Solvation in Mixed Solvents (Ⅳ). Solvolysis of Adamantyl Derivatives in Methanol-Acetonitrile Mixtures
Ikchoon Lee, Bon-su Lee, Se Chul Sohn, Byung Choon Lee
Solvolysis of 1-adamantyl chloride, -bromide and -tosylate have been studied in methanol-acetonitrile mixtures. Rate maxima were found for 1-adamantyl bromide and tosylate at 80-90 % methanol mixtures. The rate maximum observed was interpreted as a result of cooperative enhancement of cation and anion solvation. 1-Adamantyl tosylate had small cation solvation but had extensive anion solvation. It was concluded that the Y scale based on adamantyl tosylate is superior to others since it varies in a wide range especially for weakly ionizing medium.
