Palladium-Catalyzed Methylation of Aryl, Heteroaryl, and Vinyl Boronate Esters

A method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu2Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biologically active compounds via the boronate esters. The unique capabilities of this method are demonstrated by combining carbon-boron bond-forming reactions with palladium-catalyzed methylation in a tandem transformation.

New procedure for the examination of the degradation of volatile organonitrogen compounds during the treatment of industrial effluents

We present a new procedure for the determination of 32 volatile organonitrogen compounds in samples of industrial effluents with a complex matrix. The procedure, based on dispersive liquid?liquid microextraction followed by gas chromatography with nitrogen-phosphorus and mass spectrometric detection, was optimized and validated. Optimization of the extraction included the type of extraction and disperser solvent, disperser solvent volume, pH, salting out effect, extraction, and centrifugation time. The procedure based on nitrogen-phosphorus detection was found to be superior, having lower limits of detection (0.0067?2.29 mug/mL) and quantitation as well as a wider linear range. The developed procedure was applied to the determination of content of volatile organonitrogen compounds in samples of raw effluents from the production of bitumens in which 13 compounds were identified at concentrations ranging from 0.15 to 10.86 mug/mL and in samples of effluents treated by various chemical methods.

Synthesis, absorption and fluorescence spectral characteristics of trinucleus dimethine cyanine dyes as fluorescent probes for DNA detection

The preparation of six trinucleus dimethine cyanine dyes with pyridine nucleus obtained by the condensation of trimethylpyridinium iodides with heterocyclic aromatic aldehyde was described. The absorption and fluorescence properties of the dyes were studied in different polarity solvents. Blue shift of the maxima absorption of the dyes was observed with the increase of solvents polarity. The fluorescence properties of the dyes in solution and in presence of DNA were studied. Significant enhancement of the fluorescent quantum yield was observed in four dyes in the presence of DNA. Specially, one of six dyes emitted weak fluorescence in Tris-HCl buffer, but displayed bright fluorescence in the presence of DNA.

Aqua(2,4-dimethylpyridine-N)(N-salicylideneglycinato-O,N,O?) copper(II)

The CuII atom of the title complex, [Cu(C9H7NO3)-(C7H 9N)(H2O)], has a square-pyramidal coordination sphere with a tridentate N-salicylideneglycinato Schiff base dianion and a 2,4-dimethylpyridine ligand bound in the basal plane. The apex of the pyramid is occupied by an O atom from the coordinated water molecule at an apical distance of 2.416 (2) A. The monomeric moieties in the crystal are stabilized through hydrogen bonding, building a two-dimensional network. The copper(II) polyhedra are arranged in two magnetically inequivalent orientations, leading to a slightly distorted ferrodistortive coupled g tensor.
