Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, EarlyView.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Sulfur‐Directed Construction of Vinyl Cyclopropanes from 1,3‐Dienes

Angewandte Chemie, EarlyView.
Sulfur takes control. A pending thioether acts as a molecular compass, directing carbene addition to the 1,3‐diene scaffold with exceptional regio‑ and diastereocontrol to forge sulfur‐substituted vinyl cyclopropanes (S‐VCPs) — molecular architectures inaccessible via conventional cyclopropanation strategies.

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

Advanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

Angewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

Angewandte Chemie, EarlyView.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Regenerative Photocatalysis

Aiming to expand the reactivity domain of photocatalysis, we discovered the peculiar behaviour of a purely organic catalyst. Upon light irradiation, it undergoes controlled disruption, substrate activation, and regeneration in an unconventional regenerative catalytic cycle. Upon visible-light irradiation (400 nm), the molecule cleaves, generating three

Controlling Near‐Infrared Fluorescence‐to‐Phosphorescence Ratios and Triplet Lifetimes in Rhodium(I) Dimers via Primary and Secondary Coordination Sphere Effects

Angewandte Chemie, EarlyView.
RhI dimers with bridging aryl isocyanide and di‐phosphine ligands show NIR‐I or NIR‐II fluorescence/phosphorescence, depending on the ligands and conformational rigidity at the Rh2 core. Rh‐Rh interactions can be tuned by peripheral modification of the aryl isocyanide ligand, resulting in a rigid Rh2 core and improved photophysical properties ...

Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes

Angewandte Chemie, EarlyView.
Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an
