Disclosing the Mechanism and Origin of Stereoselectivity of NHC-Catalyzed Transformation Reaction of Enal with Acyl Azolium as Key Intermediate The α,β-unsaturated acyl azolium has emerged as a central reactive intermediate for reaction discovery using N-heterocyclic carbene catalysis during the past decades, whereas, the mechanistic studies on transformations of carbonyl compounds involving α,β-unsaturated acyl azolium as key intermediates are rare.

Microporous mixed-metal (Na/Cu) mixed-ligand (flexible/rigid) metal–organic framework for photocatalytic H2 generation For the first time, we report a cost-effective mixed-metal (Na/Cu) mixed-ligand (flexible/rigid) metal–organic framework H1.5[Na0.5Cu2(L1)(L2)(H2O)]·5.5H2O (Na/Cu–MOF; H2L1 = 4,4'-(4-(4H-1,2,4-triazol-4-yl)phenylazanediyl)dibenzoic acid; H4L2 = citric acid).

The rational design of completely cocatalyst-free and self-sensitized photocatalytic systems for splitting water into hydrogen is a subject of new research. As the first example without additional cocatalysts and photosensitizers, the comparatively cost-effective Cu2I2-based MOF Cu-I-bpy, exhibited a high-efficiently photocatalytic hydrogen production (7.09 mmol·g-1·h-1).
