Synergistic Catalysis for the Umpolung Trifluoromethylthiolation of Tertiary Ethers.
Angewandte Chemie, 2018The first transition-metal-free, site-specific umpolung trifluoromethylthiolation of tertiary alkyl ethers has been developed, achieving the challenging tertiary C(sp3 )-SCF3 coupling under redox-neutral conditions.

Two children are reported in whom chemical cystitis developed when ether was used to dissolve a Foley catheter balloon that would not deflate. The irritative effects of ether and preventive measures are discussed.

Catalytic transfer hydrogenolysis (CTH) of diphenyl ether (DPE), 2-phenethyl phenyl ether (PPE), and benzyl phenyl ether (BPE)—as model molecules of α-O-4 and β-O-4 as well as 4-O-5 lignin linkages—promoted by bimetallic Pd/Ni systems is reported. Pd/Ni (

Several observations made during the course of studies on stealth-adapted viruses are explainable by a pervasive, energy-rich, ether environment. Activation of an alternative cellular energy (ACE) pathway provides stealth virus damaged cells with a repair mechanism that is independent of the cellular immune response.

Chemistry and Physics of Lipids, 2011
The naturally occurring 1-O-alkyl-sn-glycerols and their methoxylated congeners, 1-O-(2'-methoxyalkyl)-sn-glycerols, are biologically active compounds, ubiquitously found in nature as diacyl glyceryl ether lipids and phosphoether lipids. The chief objective of this article is to provide a comprehensive and up to date review on such ether lipids.

AbstractUpper critical solution temperature (u.c.s.t.) phase behaviour was found in blends of the homopolymer poly(oxy‐1,4‐phenyleneoxy‐1,4‐phenylenesulphonyl‐1,4‐phenylene) (PEES) with the copolymer poly(oxy‐l,4‐phenyleneoxy‐l,4‐phenylenecarbonyl‐l,4‐phenylene‐co‐oxy‐l,4‐phenyleneoxy‐1,4‐phenylenesul‐phonyl‐1,4‐phenylene) (COPEEKS) for copolymer ...

Effect of dihydroxydiphenyl ether on poly(ether ether ketone)
Journal of Polymer Research, 1996A series of modified poly(ether ether ketone) (PEEK) polymers were synthesized by introduction of addition ether groups from dihydroxydiphenyl ether (DHDE) into the PEEK structure. The inherent viscosity of the DHDE-modified PEEK increased with reaction time at 320 °C.

Thermoreversible Gelation of Poly(ether ether ketone)
ACS Macro Letters, 2017Solutions of poly(ether ether ketone) in dichloroacetic acid have been shown to form monolithic, thermoreversible gels at temperatures ranging from 10 to 140 °C. A phase diagram was constructed over broad concentration and temperature ranges, and the phase boundary suggests an upper critical solution temperature (UCST) behavior. Furthermore, poly(ether

Anomalous diffusion in poly-ether-ether-ketone
Chemical Engineering Science, 1994Poly-ether-ether-ketone (PEEK) is a thermoplastic tough polymer used as a matrix for advanced composite materials in aeronautic applications. The investigation of its resistance to humid environment and to exposure to organic and chlorinated solvents is extremely important.
