Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

Carbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

Chemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

Spatial and Temporal Disparity Analyses of Glycosylated Benzaldehyde and Identification and Expression Pattern Analyses of Uridine Diphosphate Glycosyltransferase Genes in Prunus mume

Plants
The species Prunus mume consists of uniquely aromatic woody perennials with large amounts of free aromatic substances in the flower cells. Uridine diphosphate glycosyltransferase (UGT) modifies these free aromatic substances into water-soluble glycoside ...

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.
