Photoinduced Hydrogenative Dearomatization With Homocoupling of Quinolines to Construct Octahydro‐4,4'‐biquinolines

Chemistry – A European Journal, EarlyView.
Dearomative homocoupling of quinolines into 1,1',2,2',3,3',4,4'‐octahydro‐4,4'‐biquinoline (OHBQ) is reported. The photoexcited boron complex, in situ generated from quinoline, HB(pin), and KOtBu, enables the unprecedented homocoupling of tetrahydroquinolines that is challenging in the ground state, expanding the chemical diversity of OHBQ derivatives.

Uptake, Distribution, and Activity of Pluronic F68 Adjuvant in Wheat and Its Endophytic Bacillus Isolate

Agrochemicals
Surfactants are widely utilized in agriculture as emulsifying, dispersing, anti-foaming, and wetting agents. In these adjuvant roles, the inherent biological activity of the surfactant is secondary to the active ingredients.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes

Chemistry – A European Journal, EarlyView.
Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals

Chemistry – A European Journal, EarlyView.
Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.
