1,4‐Pentanediol as an Alternative Biomass‐Derived Medium for the Phosphine‐Free Heck Coupling Reactions

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
In this research, a phosphine‐free Heck coupling reaction was performed using biomass‐derived 1,4‐pentanediol and a polar protic solvent. It was demonstrated that a wide scope of products could be isolated by a simple filtration, eliminating the high‐solvent‐consuming column chromatography and reducing the E‐factor by more than 90% compared to ...

Catalytic Enantioselective Synthesis of Conformationally Stable C(sp2)−C(sp3) Naphthocoumarin Atropisomers

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
The enantioselective synthesis of naphthocoumarin adducts via a tandem organocatalytic 1,4‐addition/decarboxylation delivers excellent control over a newly forged stereocenter and yields configurationally stable synclinal atropisomers. The process features broad substrate scope and scalability, and its structural and mechanistic foundations are ...

From the Modeling of Experiments to the Ab Initio Prediction of Rate Constants: Statistical Rate Theory for a Quantitative Understanding of Gas‐Phase Ion Chemistry

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for

Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.

Bridging the gap between the gas and solution phase : solvent specific photochemistry in 4-tert-butylcatechol [PDF]

, 2015
Eumelanin is a naturally synthesized ultraviolet light absorbing biomolecule, possessing both photoprotective and phototoxic properties. We infer insight into these properties of eumelanin using a bottom-up approach, by investigating a subunit analogue ...

Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

Bulletin of the Korean Chemical Society, Volume 47, Issue 4, Page 484-492, April 2026.
A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...

the dilemma in Pd-catalyzed polyketone synthesis [PDF]

, 2013
A series of Pd-complexes containing nonsymmetrical bis(aryl-imino)acenaphthene (Ar-BIAN) ligands, characterized by substituents on the meta positions of the aryl rings, have been synthesized, characterized and applied in CO/vinyl arene copolymerization ...
