Reactions of complex compounds of cobalt. Part IX. Ammonia exchange during the base hydrolysis of chloropenta-amminecobalt(III) ion in concentrated aqueous ammonia

Abstract

In unsuccessful attempts to detect kinetically labile cobalt(II) species (intermediates in a postulated redox mechanism) the ammonia exchange during base hydrolysis of [Co(¹⁵NH₃)₅Cl]Cl₂ in concentrated aqueous ammonia was examined. At ca. 23 °C there was less than 1% exchange. ¹⁵N/¹⁴N analyses were done by a novel method using ¹H magnetic resonance. Experimental details are given.
