From nano- to macroarchitectures: designing and constructing MOF-derived porous materials for persulfate-based advanced oxidation processes
Chem Commun (Camb). 2024 Apr 8. doi: 10.1039/d4cc00433g. Online ahead of print.ABSTRACTPersulfate-based advanced oxidation processes (PS-AOPs) have gained significant attention as an effective approach for the elimination of emerging organic contaminants (EOCs) in water treatment. Metal-organic frameworks (MOFs) and their derivatives are regarded as promising catalysts for activating peroxydisulfate (PDS) and peroxymonosulfate (PMS) due to their tunable and diverse structure and composition. By the rational nanoarchitectured design of MOF-derived nanomaterials, the excellent performance and customized functions can be achi...

Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates
Chem Commun (Camb). 2024 Apr 5. doi: 10.1039/d4cc00522h. Online ahead of print.ABSTRACTQuaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of styrene carbonate at moderate temperature (80 °C).PMID:38577743 | DOI:10.1039/d4cc00522h (Source: Chemical Communications)

Copper(I)-free syntheses of [ 11 C/ 18 F]trifluoromethyl ketones from alkyl or aryl esters and [ 11 C/ 18 F]fluoroform
Chem Commun (Camb). 2024 Apr 5. doi: 10.1039/d4cc00465e. Online ahead of print.ABSTRACTHerein, we report a copper(I)-free method for labeling the trifluoroacetyl group with positron-emitting carbon-11 (t1/2 = 20.4 min) or fluorine-18 (t1/2 = 109.8 min) as part of our exploration of radiolabeled fluoroforms to access new radiolabeled chemotypes of interest for tracer development. Treatment of alkyl esters and aryl esters, containing electron-donating or electron-withdrawing groups, with [11C/18F]fluoroform in the presence of strong base, gave [11C/18F]trifluoromethyl ketones as novel radiolabeling synthons in moderate to hi...
