Abstract
Podands based on benzimidazol-2(1H)-one, containing S and terminal NH2 groups, selectively transport and extract silver picrate over Mg2+, Ca2+, Sr2+, Ph2+ and Tl+ picrates.

All compounds give satisfactory spectral and mass and/or analytical (in case of solids) data.
In all these cases Mg2+ and Ca2+ picrates are extracted and transported at much lower rates than other cations.
