Applications of QSPR and Machine Learning in Molecular Photonics

Advanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

Ultrashort‐Pulsed Laser Diffusion Enhancement in Liquids for Cold Extraction of Coffee in an Analytically Validated Low‐Fluence Regime

Advanced Photonics Research, EarlyView.
In this article, pulsed laser diffusion enhancement in liquids as an analytically validated laser extraction in liquids method of coffee suspensions in a defined low fluence window is presented. The results confirm the generation of a unique aroma profile and reduced acidity, which is neither attributed to changes in the specific surface area nor ...

Water‐Mediated 1,7‐Palladium Aryl‐to‐Aryl Migration in an Unusual Aryne Trimerization Enables the Synthesis of Multihelicenes with Profoundly Hindered Stereogenic Axes

Advanced Synthesis &Catalysis, EarlyView.
In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Cooperative Photocatalysis of 9,10‐Phenanthrenequinone and Sn(OTf)2 for Direct Mannich Reaction of Ethers via Hydrogen Atom Transfer Pathway

Advanced Synthesis &Catalysis, EarlyView.
A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A

Thioether Synthesis via the Nickel‐Catalyzed Electrochemical Cross Electrophile Coupling of Aryl/Alkyl Disulfides and Aryl/Alkyl Halides

Advanced Synthesis &Catalysis, EarlyView.
A nickel catalyzed electrochemical cross‐electrophile coupling approach for the base‐free synthesis of (un)symmetric (hetero)aryl and alkyl sulfides from organic halides and disulfides is described. The reaction is broadly applicable and tolerates water and air atmosphere. A formal cross‐electrophile coupling approach enables the base‐free synthesis of
