Synthesis of azacrown sulfonamides via ring closing metathesis and their evaluation in lithium ion selective electrodes

Abstract

New diazapolyoxa macrocyclic ditosylates with 17-28-membered rings were synthesized by the application of the RCM technique to suitable α,ω-dienes. These compounds were employed as neutral carriers in Li+-selective electrodes. The electrodes exhibited nearly Nernstian responses with relatively high selectivity for lithium over other inorganic cations. ©ARKAT-USA, Inc.
