A STUDY OF NUCLEOPHILIC SUBSTITUTION REACTIONS OF TRIS(1,10-PHENANTHROLINE) NICKEL(II) AND TRIS(1,10-PHENANTHROLINE) IRON(II) CATIONS.
Abstract
The dissociation rate of tris (1,10-phenanthroline) nickel(II) ion was followed by the extraction of released 1,10-phenanthroline into dichloromethane and its subsequent spectrophotometric analysis as the iron(II) complex. The racemization rate of tris (1,10-phenanthroline) - nickel(II) ion was found to be equal to the dissociation rate of the tox oxx In 1.0 M sodium hydroxide there complex in 1.0 M sodium hydroxide. was a 25% increase water. in the racemization rate compared to that in pure The increase was not considered significant as ionic strength control could not be maintained because of the low solubility of the complex at high ionic strengths. Up to 1.2 cyanide and azide ion concentrations showed no effect on the dissociation rate of the nickel(II) complex.
