Non-Noble-Metal Metal-Organic-Framework-Catalyzed Carboxylative Cyclization of Propargylic Amines with Atmospheric Carbon Dioxide under Ambient Conditions.

The coupling reaction of propargylic amines and carbon dioxide (CO) to synthesize 2-oxazolidinones is an important reaction in industrial production, and yet harsh reaction conditions and noble-metal catalysts are often required to achieve high product yields. Herein, one novel noble-metal-free three-dimensional framework, [MgCuI(IN)(HCOO)(DEF)] (), assembled by magnesium and copper clusters was synthesized and applied to this reaction. Compound displays excellent solvent stability.

A Porous Copper-Organic Framework Assembled by [Cu] Nanocages: Highly Efficient CO Capture and Chemical Fixation and Theoretical DFT Calculations.

A new porous copper-organic framework assembled from 12-nuclear [Cu] nanocages {[Cu(L)(HO)]·4DMA·2HO} () (HL = 5,5'-(butane-1,4-diyl)-bis(oxy)-diisophthalic acid) was successfully prepared and structurally characterized. Compound feathering of a 3D framework with two types of 1D nanotubular channels and a large specific surface area can effectively enrich various harmful dyes. Additionally, due to the carbon dioxide (CO) interactions with open Cu(II) sites and the electron-rich ether oxygen atoms of ligand in , it exhibits a highly selective CO uptake.

Solvent-Dependent Assembly and Magnetic Relaxation Behaviors of [CuI] Cluster-Based Lanthanide MOFs: Acting as Efficient Catalysts for Carbon Dioxide Conversion with Propargylic Alcohols.

Two structurally similar metal-organic frameworks (MOFs) [DyCuI(IN)(DMF)]·DMF () and [DyCuI(IN)(DMA)]·DMA () (HIN = isonicotinic acid) feathering different coordinated solvent molecules were successfully isolated by tuning the types of solvents in the reaction system. Structural tests indicate that and are both built from 1D Dy(III) chains and copper iodide clusters [CuI], generating into three-dimensional frameworks with an open 1D channel along the axis. and display extensive and excellent solvent stability.

[Comparison of the clinical therapeutic effects between local injection of pingyangmycin and sodium morrhuate on oral and maxillofacial venous malformation].

Objective: To observe and compare the curative effect of pingyangmycin and sodium morrhuae respectively in the treatment of oral and maxillofacial venous malformation.

Methods: Forty cases of oral and maxillofacial venous malformation were induced in this study, 20 of which were given local injection of low dose of pingyangmycin, and 20 given local injection of 5% sodium morrheate. The therapeutic effects were observed.
