Stereoselective Synthesis of 5-7 membered Cyclic Ethers by Deiodonative Ring-Enlargement Using Hypervalent Iodine Reagents [PDF]
Stereoselective synthesis of 5-7 membered cyclic ethers was achieved by deiodonative ring-enlargement of cyclic ethers having an iodoalkyl substituent.

Efficient synthesis, characterization and electrochemical properties of bis(ferrocenyl) ethers
Three different symmetrical ethers derived from formyl ferrocene, acetyl ferrocene and benzoyl ferrocene have been characterized via FT-IR, UV-Visible and 1H NMR spectroscopic techniques. Further, the true nature of bis[phenyl(ferrocenyl)methyl]ether was

Investigation of the stability of azacrown complexes with some transition metal ions [PDF]
The separation of metal ions from nuclear waste is an important issue in the nuclear industry. Cyclic chemical compounds including ether groups are called crown ethers. These compounds strongly bind to certain cations, forming complexes.

Synthesis and desulfurization-decarboxylation of cyclic thionocarbonates of glycerol 1-ethers
A method is described for the synthesis of cyclic thionocarbonates of 1-O-alkyl glycerols in quantitative yield. These derivatives of glycerol ethers can be quantitated by UV absorbance, analyzed by gas-liquid chromatography, or quantitatively converted ...
