Deuterium Isotope Effects on the Acid Hydrolysis Rates of Chloro Complexes of Cobalt(III)1
Deuterium substitution both in the complex and in the solvent slows the rate of acid hydrolysis of chlorocomplexes of cobalt(III). This is similar to what is observed in the solvolysis reactions of organic halides and the same explanations may be used. The isotope effect In the base hydrolysis of Co(NH/ sub 3/)/sub 5/Cl/sup +2/ is consistent with, but does not prove, an SnlCB mechanism. (auth)
