Diazonium ions, inorganic

We will review that comparison in the context of the discussion of aliphatic and inorganic diazonium ions in our second book (Zollinger, 1995, Sec. 5.3). 

Two inorganic nucleophiles that react easily with arenediazonium ion, namely the nitrite ion and the hydroxide ion, provide good examples of the concept of the nucleophilic homolytic leaving group. By electron transfer to a diazonium ion the... 

The guest cations hitherto examined cover broadly uni- to trivalent and inorganic to organic ions that include alkali, alkaline earth, heavy and transition metal ions, as well as (ar)alkyl ammonium and diazonium ions. As to the complex stoichiometry between cation and ligand, both 1 1 stoichiometric and 1 2 sandwich complexes are analyzed. The solvent systems employed also vary widely from protic and aprotic homogeneous phase to binary-phase solvent extraction. 

The availability of superacid systems made it possible to study some further inorganic diazonium ions. 

All inorganic diazonium ions (X-Ni ) discussed in Section 3.1 are characterized structurally, first, by a small group X consisting of one to five atoms, and, second, by little or no stabilization of the X —N(a) bond. These inorganic diazonium ions are, therefore, comparable to simple aliphatic diazonium ions, e.g., H3C Ni. ... 

Phenyldiazonium chloride and other similar diazonium compounds are very soluble in water, are completely insoluble in ether and other organic solvents, and are completely dissociated in aqueous solution to organic cations and inorganic anions (e.g., chloride ions) a convenient formulation is therefore, for example, CjHjNj+CP.
