, 2016 A 3-step asymmetric approach toward the optically active chiral cyclohex-2-enones from anisoles has been developed. The crucial asymmetric induction step is an unprecedented catalytic enantioselective isomerization of β,γ-unsaturated cyclohex-3-en-1-ones

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

NMR-spectroscopic study of conjugation effects. 8.13C NMR spectra of p-substituted anisoles, thioanisoles, and selenoanisoles [PDF]
, 1980 1. According to the data from13C NMR spectra, the effective conformation of anisoles, thioanisoles, and selenoanisoles is determined both by "methyl-ring" spatial interactions as well as by p, π conjugation of the O, S, and Se with the aromatic fragment ...

One-Step Preparation of Some 3-Substituted Anisoles
, 2016 A one-step preparation of 3-bromoanisole, 3-chloroanisole, and 3-trifluoromethylanisole from the corresponding 3-substituted nitrobenzenes is carried out by nucleophilic aromatic substitution of the nitro group with sodium or potassium methoxide ...

1,2‐Bis(boronate) Arenes by Borylation Directed Borylation
Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.Boron electrophiles derived from tetrabromo‐pyrazaboles and AlCl3 affect the regioselective vicinal double C–H borylation of a range of arenes and polycyclic aromatic hydrocarbons (PAHs). A subsequent pinacol installation step then affords the vicinal bis‐boronate ester‐substituted arene/PAH.

Cl NQR Studies in 2,4,6-, 2,3,6-, and 2,3,4-Trichloro Anisoles
, 1985 The chlorine-35 NQR frequencies and their temperature variation in 2,4,6-, 2,3,6- and 2,3,4-trichloro anisoles have been studied and compared with the corresponding chlorophenols with a view to studying the effect of hydrogen bonding.

Some spectroscopic, kinetic and equilibria studies of Cyano- and nitro- substituted anisoles and phenols and their reactions with nucleophiles [PDF]
, 1990 The reactions of ring-activated alkyl aryl ethers with nucleophiles have been examined. The main pathways involve attack by the nucleophiles at the alkyl carbon to give substituted phenoxide ions, or at ring carbon atoms to give σ-adducts.

Advanced Photonics Research, Volume 7, Issue 11, November 2026.Efficient persistent deep‐red emission is achieved in purely organic systems at elevated donor concentrations via triplet–singlet Förster‐resonance energy transfer. A high phosphorescence quantum yield of 53.6% is obtained at 10 wt% donor loading, and remains as high as 37.2% even at 30 wt%.

Advanced Science, Volume 13, Issue 62, 9 November 2026.A transpiration‐inspired Janus nanofiber membrane creates a persistent dry‐wet interface that couples localized solar heating with hydration‐induced ion regulation. The asymmetric architecture sustains directional water and ion transport, suppresses salt accumulation, and enables simultaneous seawater evaporation and stable electricity generation ...
