Novel carrier molecules: lipophilic ammonium ylides for membrane transport of metal picrates

Institute of Organic Chemistry and Biochemistry
Publication Date


The novel artificial carriers have been synthesized by introduction of lipophilic group of pyrrolidinomalonaldehyde and N-imidazolylmalonaldehyde.. These stable dipolar synthetic carriers were used for transport of metal picrates through a liquid membranes. The cation specificity of the transport was determined by the means of atomic absorption spectroscopy. Carrier properties of ylides were compared with N,N-dimethyldodecylamine N-oxide and DB18C6. The formation of complexes of ylides with some inorganic salts by the means of NMR spectroscopy, X-ray and potentiometric measurements of KS have been studied.
