Controllable encapsulation of silver nanoparticles by porous pyridine-based covalent organic frameworks for efficient CO2conversion using propargylic amines

The conversion of CO2 into value-added chemicals is an attractive alternative to produce valuable fuels and chemicals. In this work, we demonstrate two pyridine-based covalent organic frameworks (COFs) with rich porosity for the size-controlled synthesis

Highly Efficient Conversion of Propargylic Amines and CO2 Catalyzed by Noble-Metal-Free [Zn116] Nanocages

The reaction of propargylic amines and CO2 can provide high-value-added chemical products. However, most of catalysts in such reactions employ noble metals to obtain high yield, and it is important to seek eco-friendly noble-metal-free MOFs catalysts. Here, a giant and lantern-like [Zn116] nanocage in zinc-tetrazole 3D framework [Zn22(Trz)8(OH)12(H2O)9?8 H2O]n Trz=(C4N12O)4? (1) was obtained and structurally characterized. It consists of six [Zn14O21] clusters and eight [Zn4O4] clusters. To our knowledge, this is the highest-nuclearity nanocages constructed by Zn-clusters as building blocks to date. Importantly, catalytic investigations reveal that 1 can efficiently catalyze the cycloaddition of propargylic amines with CO2, exclusively affording various 2-oxazolidinones under mild conditions. It is the first eco-friendly noble-metal-free MOFs catalyst for the cyclization of propargylic amines with CO2. DFT calculations uncover that ZnII ions can efficiently activate both C≡C bonds of propargylic amines and CO2 by coordination interaction. NMR and FTIR spectroscopy further prove that Zn-clusters play an important role in activating C≡C bonds of propargylic amines. Furthermore, the electronic properties of related reactants, intermediates and products can help to understand the basic reaction mechanism and crucial role of catalyst 1.

An expeditious and atom-economic synthesis of lead-like, medicinally important 4,5-dihydropyrazolo[1,5-a]pyrazin-6-ones

We have developed an expeditious and atom-economic synthesis of lead-like, privileged 4,5-dihydropyrazolo[1,5-a]pyrazin-6-ones, which is based on Sonogashira coupling and a two-step condensation with hydrazine hydrate leading to two ring-forming events, with full control over the two elements of diversity present.
