Photochemistry and Photobiology, EarlyView.This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Photochemistry and Photobiology, EarlyView.Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

Two new benzophenones from endohydric moss Polytrichum Commune
, 2018 Two new benzophenones (1 and 2), were isolated from the endohydric moss Polytrichum commune. Their structures were elucidated by spectroscopic methods including extensive 2 D NMR techniques.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods
Chirality, Volume 38, Issue 7, July 2026.Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

THE PREPARATION OF SOME SUBSTITUTED BENZOPHENONES AND BENZOHYDROLS
, 1950 Six benzophenones and their corresponding benzohydrols have been prepared. The former were obtained through the extension of a method employed by Boeseken for the preparation of benzophenone dichloride by the action of carbon tetrachloride on benzene in

An Electron‐Poor Nickel Diphosphine Complex: Synthesis, Structure, and Reactivity of Ni(dFppe)2
Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.Fluorinated diphosphine ligands such as 1,2‐bis[bis(pentafluorophenyl)phosphino]ethane (dFppe) offer powerful electronic tunability and unusual reactivity. Despite known analogues of the heavier congeners Pd and Pt, Ni complexes of dFppe remain conspicuously absent.

Sterically Hindered Benzophenones via Rhodium-Catalyzed Oxidative Arylation of Aldehydes
, 2008 Efficient cross-coupling, allowing a straightforward access to congested benzophenones, between aromatic aldehydes and potassium aryltrifluoroborates, is described in the presence of a rhodium/tri-tert-butylphosphane catalyst system and acetone as ...
