Efficient Cycloaddition of CO2and Aziridines Activated by a Quadruple-Interpenetrated Indium-Organic Framework as a Recyclable Catalyst

On the basis of the global warming effect, it is of great significance to convert CO2 into the high value-added products oxazolidinones, but investigations on main-group-based metal-organic frameworks (MOFs) as heterogeneous catalysts still have not been

An uncommon multicentered ZnI-ZnIbond-based MOF for CO2fixation with aziridines/epoxides

A novel cluster-based MOF with uncommon multicentered ZnI-ZnIbonds {[K1.2Na2.8ZnI8(HL)12]·4H2O}n(HL = tetrazole monoanion) (1) was synthesized, which showed higher stability than the reported ZnI-ZnIbonded compounds. Moreover,1can effectively and circularly catalyze the cyclization of CO2and aziridines or epoxides with five substituent groups. Importantly, this is the first time that the catalytic properties of MOFs with multicentered metal-metal bonded clusters as the catalyst have been studied.

Two Stable Heterometal-MOFs as Highly Efficient and Recyclable Catalysts in the CO2 Coupling Reaction with Aziridines

Two stable heterometal-organic frameworks, {Na[LnCo(DATP)2(Ac)(H2O)](NO3)?DMA?11 H2O}n (Ln=Er(1) and Yb(2)), have been prepared with H2DATP (4′-(3,5-dicarboxyphenyl)-2,2′:6′,2′′′-terpyridin

Cycloaddition of Aziridine with CO2/CS2 Catalyzed by Amidato Divalent Lanthanide Complexes

This is the first time that the amidato lanthanide amides ({LnLn[N(SiMe3)2]THF}2 (n = 1, Ln = Eu (1); n = 2, Ln = Eu (3), Yb (4); HL1 = tBuC6H4CONHC6H3(iPr)2; HL2 = C6H5CONHC6H3(iPr)2) and {L3Eu[N(SiMe3)2]THF}{L32Eu(THF)2} (2) (HL3 = ClC6H4CONHC6H3(iPr)2)) were applied in the cycloaddition reactions of aziridines with carbon dioxide (CO2) or carbon disulfide (CS2) under mild conditions. The corresponding oxazolidinones and thiazolidine-2-thiones were obtained in good to excellent yields with good functional group tolerance.

A multifunctional MOF as a recyclable catalyst for the fixation of CO2 with aziridines or epoxides and as a luminescent probe of Cr(VI)

A multifunctional metal-organic framework (1) containing 24-nuclear zinc nanocages shows high solvent- and pH-stability. Compound 1 can be employed as a catalyst for the conversion of CO2 with aziridines or epoxides, which can be reused at leas

Proline-catalyzed synthesis of 5-aryl-2-oxazolidinones from carbon dioxide and aziridines under solvent-free conditions

Natural a-amino acids were proven to be ecofriendly and recyclable catalysts for the carboxylation of aziridines with CO2 without utilization of any organic solvents or additives. Notably, a series of 5-aryl-2-oxazolidinones were obtained in go

Preparation of polystyrene-supported Lewis acidic Fe(III) ionic liquid and its application in catalytic conversion of carbon dioxide

A polystyrene-supported Lewis acidic iron-containing ionic liquid was proved to be recyclable and efficient heterogeneous catalyst for converting CO2 into cyclic carbonate without utilization of any organic solvent or additive. Excellent yields and selectivity were obtained under mild reaction conditions. Notably, the catalyst could be readily recovered and reused over five times without appreciable loss of catalytic activity. A possible catalytic cycle was proposed. The present protocol has successfully been applied to reactions of aziridines/propargyl amines with CO2. This kind of the catalyst presented herein would have great potential in industrial application thanks to its featured advantages.

Regioselective synthesis of 5-aryl-2-oxazolidinones from carbon dioxide and aziridines using Br- Ph3+PPEG 600P+Ph3Br- as an efficient, homogenous recyclable catalyst at ambient conditions

Polyethylene glycol functionalized phosphonium salt (Br- Ph 3+PPEG600P+Ph3Br -) was found to be an efficient, homogenous, recyclable catalyst for coupling of CO2 with a variety of aziridines producing corresponding 5-aryl-2-oxazolidinones with good yields and excellent regioselectivity under relatively mild and solvent free conditions. Furthermore, the catalyst was effectively recycled for four consecutive cycles without any significant loss in its catalytic activity and selectivity.

Protic onium salts-catalyzed synthesis of 5-aryl-2-oxazolidinones from aziridines and CO2 under mild conditions

Protic onium salts, e.g. pyridium iodide, proved to be highly efficient and recyclable catalysts for the selective synthesis of 5-aryl-2-oxazolidinones under a CO2 atmosphere at room temperature, presumably due to aziridine activation assisted by hydrogen bonding on the basis of 1H NMR and in situ FT IR under CO2 pressure study.

Polystyrene-supported amino acids as efficient catalyst for chemical fixation of carbon dioxide

Four new polystyrene-supported amino acids have been synthesized and applied to the chemical fixation of carbon dioxide for the first time. Two series of experiments with polystyrene-supported threonine (PS-Thr) and polystyrene-supported tyrosine (PS-Tyr) as catalyst, respectively, were conducted to study the effect of the reaction conditions on the carboxylation of propylene oxide/carbon dioxide. There was no considerable decrease in the yield of propylene carbonate after the polystyrene-supported amino acids were used five times, indicating that these catalysts are very stable. It was demonstrated that these catalysts were very efficient in the carboxylation of various epoxides and aziridines with carbon dioxide under mild conditions without any solvents. The mechanism for this carboxylation is also discussed.
