Synthesis of Crown Ethers Containing a Sulfide Group Inside the Ring and High Ag+ Selectivity in Solvent Extraction
Crown ethers bearing a sulfide, a sulfoxide, or a sulfone group inside the ring have been prepared and the sulfide derivatives exhibit a significantly high Ag+ selectivity in solvent extraction.
