Abstracts

EN

Two bifunctional sulfur-silicon nucleophilic ionophores 3-(trimethoxysilyl)-propanethiol (Nu1) and 3-(tri-2-methoxyethoxysilyl)-propanethiol (Nu2) were used as reagents in the acyl transfer reaction studied by kinetic methods. Nuclear magnetic resonance (NMR) and electro-spray ionisation mass spectrometry (ESI MS) were used for determination of the stoichiometry and stability constants of the complexes made by the podands and lithium or sodium ions in acetonitrile solution.
