Abstract

The ^13^C NMR spectrum of dithizone, unlike that of its oxygen analogue, shows only five different types of carbon atom. The ^13^C chemical shift of the Cο£ΎS group in dithizone is only 7 ppm to lower field of that of the Cο£ΎO moiety in its analogous compound. The results can be rationalized by consideration of tautomeric equilibria which lead to C~2v~ time‐averaged symmetry.

The formation of a complex ML,, in the aqueous phase of a two-phase system from a metal ion M+n, present initially in the aclueous phase, and the ligand L-, derived from the conjugate acid HL originally present in the non-aqueous phase, and the subsequent extraction of the complex, may be considered
