Abstract

We report the synthesis of a new 1,2-(1,2-bis-sulfoxide-12-crown-4)-ortho-carborane (12C4SOCb) and its selective chemical and electrochemical capture of Li⁺ from mixed metal (Li⁺/Na⁺/K⁺) solutions upon 2e^- reduction to its nido state. The synthesis and characterization of closo-12C4SOCb, nido-, and the Li⁺-captured nido salt, , are reported. Bulk electrolysis of 12C4SOCb in the presence of various mixed metal alkali salt solutions in organic media, coupled with ICP-OES measurements, reveal highly selective Li⁺ capture and release against competing ions, enabling its selective separation.
