A mechanistic insight into the organocatalytic properties of imidazolium-based ionic liquids and a positive co-solvent effect on cellulose modification reactions in an ionic liquid

Detailed insights into the organocatalytic properties of imidazolium-based ionic liquids (Im-ILs) for transesterification of cellulose with isopropenyl acetate (IPA) are presented. According to model transesterification reactions and their computational analysis, acetate anions of Im-ILs play an essential role in the promotion of the reactions. Mechanistic considerations in the optimization of the protocol of IL-catalyzed transesterification reactions have enabled a significant improvement in reaction conditions and a positive co-solvent effect for cellulose modifications in an imidazolium acetate ionic liquid.

NHC-Palladium(II) Mononuclear and Binuclear Complexes Containing Phenylene-Bridged Bis(thione) Ligands: Synthesis, Characterization, and Catalytic Activities

A series of mono- and binuclear Pd(II) complexes with N-heterocyclic carbene (NHC) and phenylene-bridged bis(thione) (SCS) ligands were prepared and characterized by 1H and 13C NMR spectroscopy, IR, and mass spectrometry. The molecular structures of 1b, 2a, and 3b have been determined by the single-crystal X-ray diffraction method. The catalytic activities of the synthesized palladium complexes in the regioselective reduction of quinolines to the corresponding 1,2,3,4-tetrahydroquinolines were thoroughly investigated with ammonia-borane under mild reaction conditions. It is observed that the activities of the binuclear Pd(NHC) complexes were higher than those of the corresponding mononuclear complexes under the same conditions.

Novel bifunctional chiral squaramide-amine catalysts for highly enantioselective addition of mono-and diketones to nitroalkenes

Novel bifunctional chiral squaramide-amine organocatalysts have been developed by rational combination of pyrrolidine and a cinchona alkaloid. The catalysts promoted the enantioselective Michael addition of both mono-and diketones to a broad range of nitroalkenes providing the corresponding products in moderate to high yields with excellent enantioselectivities and diastereoselectivities (up to 96% yield, 96% ee, 98:2 dr) under mild conditions. These results demonstrate that the assembly of two chiral privileged skeletons, pyrrolidine and cinchonine with a squaramide linker is a useful strategy to reach a wider substrate scope, high reaction efficiency and enantioselectivity. The match of the chiralities between two backbones embedded in the catalysts is also critical for improving enantioselectivity. ARKAT-USA, Inc.

Thirteen cationic ionophores: Their acute toxicity, neurobehavioral and membrane effects

Thirteen cationic ionophores (12-Crown-4, 15-Crown-5, 18-Crown-6, Dibenzo 18-Crown-6, Dicyclohexano 18-Crown-6, 24-Crown-8, Dicyclohexano 24-Crown-8, Lasalocid, Hexacyclen trisulfate, Chiral binapthol, Valinomycin, Monensin, and A-23187) were evaluated for acute toxicologic properties, including lethality and neurobehavioral effects in multiple species (rats, rabbits, and mice) by multiple routes, skin and eye irritation and effects on membrane permeability to physiologic cations. Attention was focused on determining minimum neurobehavioral effect levels and characterizing the spectrum of these effects at different dose levels. While LD50’s followed one pattern, this was not the case with other effects. Cluster and factor analysis suggest that, though the primary mechanism of action is alteration of membrane permeability to specifi-cations (qualitative types of activity correlate with the results of membrane permeability studies), which ions are provided an increased passage varies with ring size and charge dispersion. In the intact animal absorption markedly modifies these results.

Facile preparation and dual catalytic activity of copper(i)-metallosalen coordination polymers

Three copper(i)-metallosalen coordination polymers (CPs), {[NiII(SalImCy)]2(CuICN)9}n (1), {[CuII(SalImCy)]2(CuICN)9}n (2) and {[NiII(SalImCy)](CuII)2¡¤DMF}n (3) were prepared by direct combination of NiII/CuII(salen) motifs with [CuICN]n chains and Cu2I2 clusters via the metalloligand strategy. The mixed-valence and mixed-metal CPs could effectively catalyze both the oxidation of aromatic alcohols to ketones and aldehydes under mild conditions and photocatalytic degradation of organic dye methylene blue (MB). This work demonstrates the effective integration of transition metal catalytic NiII/CuII(salen) units and photoactive copper(i) species in a single solid polymer to meet the demand for catalytic materials with the dual catalytic properties.

Terminal uranium(V)-nitride hydrogenations involving direct addition or Frustrated Lewis Pair mechanisms

Despite their importance as mechanistic models for heterogeneous Haber Bosch ammonia synthesis from dinitrogen and dihydrogen, homogeneous molecular terminal metal-nitrides are notoriously unreactive towards dihydrogen, and only a few electron-rich, low-coordinate variants demonstrate any hydrogenolysis chemistry. Here, we report hydrogenolysis of a terminal uranium(V)-nitride under mild conditions even though it is electron-poor and not low-coordinate. Two divergent hydrogenolysis mechanisms are found; direct 1,2-dihydrogen addition across the uranium(V)-nitride then H-atom 1,1-migratory insertion to give a uranium(III)-amide, or with trimesitylborane a Frustrated Lewis Pair (FLP) route that produces a uranium(IV)-amide with sacrificial trimesitylborane radical anion. An isostructural uranium(VI)-nitride is inert to hydrogenolysis, suggesting the 5f1 electron of the uranium(V)-nitride is not purely non-bonding. Further FLP reactivity between the uranium(IV)-amide, dihydrogen, and triphenylborane is suggested by the formation of ammonia-triphenylborane. A reactivity cycle for ammonia synthesis is demonstrated, and this work establishes a unique marriage of actinide and FLP chemistries.

Harvesting New Chiral Phosphotriesters by Phosphorylation of BINOL and Parent Bis-phenols

A systematic study on the phosphorylation of BINOL and other bis-phenols with chlorophosphates is described. An intriguing reactivity has been observed that is attributable to the hydroxyl group acidity and to the leaving group nucleofuge character within the phosphorylating agent used. By playing on these two parameters, new chiral monophosphotriesters, symmetrical homo-BINOL bisphosphates, and unsymmetrical non-homo-BINOL derivatives incorporating a non-chiral side unit, were synthesized selectively and in good yields.
