Effect of dihydroxydiphenyl ether on poly(ether ether ketone)

Journal of Polymer Research, 1996
A 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.

Catalytic Transfer Hydrogenolysis of Lignin-Derived Aromatic Ethers Promoted by Bimetallic Pd/Ni Systems

ACS Sustainable Chemistry and Engineering, 2018
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 (

Synergistic Catalysis for the Umpolung Trifluoromethylthiolation of Tertiary Ethers.

Angewandte Chemie, 2018
The 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.
