Heberle, Martin published the artcileBispalladacycle Catalyzed Nucleophilic Enantioselective Allylation of Aldehydes by Allylstannanes, Product Details of C9H10O3, the main research area is aldehyde allylstannane palladacycle catalyst nucleophilic enantioselective allylation; homoallylic alc preparation.

The first palladium catalysts capable of controlling asym. nucleophilic allylations of aldehydes with allyltributyltin was reported. TONs up to 620 were achieved, which is significantly higher than for any other reported catalyst. The method also tolerated electronically and sterically unfavorable substrates. It was showed that transmetallation occurred, favoring an η1-allyl coordination mode with the bispalladacycles. In contrast, for the corresponding monopalladacycle an unproductive η3 coordination was dominant.

A three-component synthesis of 1,5-disubstituted 1,2,3-triazoles from α-acetyl-α-diazomethane sulfonamides, primary aliphatic amines and aromatic aldehydes is presented. The 1,2,3-triazoles can be accessed in two alternative variants, depending on the substitutions in the sulfonamide portion of the diazo reagent. In one variant, intermediate 1,2,3-triazoline-4-sulfonamides are isolated chromatog. and then subjected to thermally promoted aromatization with elimination of sulfur(IV) oxide and amine. In the other variant, both chem. transformations take place in a single step conducted at room temperature

Kwamen, A. Carel N. published the artcileSolvent Dependence of the Monomer-Dimer Equilibrium of Ketone-Substituted Triscatecholate Titanium(IV) Complexes, Product Details of C9H10O3, the main research area is titanium triscatecholate preparation monomer dimer equilibrium solvent effect; helicates; intermolecular interactions; self assembly; solvent effect; thermodynamics.

Hierarchical helicates based on ketone-substituted titanium(IV)triscatecholates show different monomer-dimer behavior depending on different solvents. The dimerization constants of a whole series of differently alkyl-substituted complexes is analyzed to show that the solvent has a very strong influence on the dimerization. Hereby, effects like solvophobicity/philicity, sterics, electronics of the substituents and weak side-chain-side-chain interactions seem to act in concert.

A metal-free approach to 3,4-diarylpyrrole-2-carboxylate and pyrrolocoumarin cores of lamellarins and related natural products based on Barton-Zard reaction of nitrostilbenes with Et isocyanoacetate was developed. In the case of diarylpyrrole-2-carboxylates with a 3-(o-methoxyphenyl) fragment, treatment with 1 equivalent of BBr3 resulted in selective O-demethylation of the ortho-methoxy group, while other methoxy groups in the mol. remained intact. The resulting 3-(2-hydroxyphenyl)pyrrole-2-carboxylates underwent base-induced lactonization to form the target pyrrolocoumarins.

Wang, Weigang published the artcileOrganic compounds evolution and sludge properties variation along partial nitritation and subsequent anammox processes treating reject water, Safety of 2,3-Dimethoxybenzaldehyde, the main research area is organic compound sludge nitritation anammox wastewater treatment; Denitrification; Nitrogen removal; Organic compounds evolution; Partial nitritation-anammox; Reject water.

Reject water contains complex components of organic compounds, which have significant influences on the nitrogen removal performance when treated using biol. autotrophic nitrogen removal technol. In this study, a two-stage partial nitritation (PN)-anammox (floc-granule) system was established to treat reject water (COD/NH+4-N = 0.97 ± 0.15), and the evolution of organic compounds along PN and annamox bioreactors was investigated using gas chromatog.-mass spectrometry and excitation-emission matrix. Also, the variation of PN and anammox sludge properties relating to COD reduction was examined The PN-anammox system removed approx. 80% of total inorganic nitrogen and COD with hydraulic reaction time of 16 h. The influent organics (330-600 mg COD/L) in reject water were primarily composed of volatile, protein-like and humic acid-like organic compounds PN process contributed 53 ± 18% of the overall COD removal, primarily including oxygen-containing organics (e.g. phenol), proteins and humic acids. Anammox process contributed 22 ± 15% of the overall COD removal, but large mol. acids (e.g. lactic acid) and small mol. alcs. (e.g. glycerol) were reoccurred, contributing to the effluent COD with recalcitrant hydrocarbons (e.g. n-Octadecane). Reject water increased the extracellular proteins/polysaccharides ratio of PN and anammox sludge, promoting the adsorption and degradation of organic compounds High-throughput sequencing results showed that denitrifying bacteria of Ottowia increased from 0.03% to 14.4% in PN reactor, and of Denitratisoma increased from 9.6% to 15.4% in anammox reactor. The occurrence of these denitrifiers might mitigate the neg. impact of organics to functional organisms. This study highlights the organics fate during PN-anammox treatment system, which is important to maintain the robust nitrogen removal when treating organics-containing and high ammonium concentration wastewater.
