New adducts with the composition [Co2Gd(NO3)(Piv)6L2] (L=2,4-lutidine (lut) (1), 2-phenylpyridine (PhPy) (4), 2-ethynylpyridine (EtPy) (5)) and [Co2Eu(NO3)(Piv)6(EtPy)2] (6) were synthesized. According to X-ray diffraction data, the molecular complexes comprise two atoms of cobalt(II) and one central atom of gadolinium(III) bridged by carboxylate ligands. The donor base molecules are coordinated to cobalt atoms. Magnetic measurements of the new and previously synthesized complexes with quinoline (2) and pyridine (3) ligands showed the ferromagnetic nature of the coupling between the metal centers in the CoII 2GdIII core with JCo-Gd parameters in the range of 0.15?0.18 cm?1. DFT calculations supported the ferromagnetic type of coupling for these complexes. Simultaneous thermal analysis of 1 and 2 showed the thermal stability of the complexes up to 180 C and the stepwise nature of thermolysis, which includes the stages of elimination of the donor base molecules and the thermal decomposition of the pivalate moieties in the complex.

Dimedone enamines were applied for the first time as new dienophiles in hetero-Diels-Alder reactions with inverse electron demand. Cycloadditions of barbituric acid 5-ylidene alditols with dimedone enamines were performed in dichloromethane at room temperature for 3 days and fused uracils-chromeno[2,3-d]pyrimidine-2,4-diones were obtained in good 73-87% yields. Only one enantiomerically pure stereoisomer was obtained in each studied cycloaddition. Analysis of 1H NMR and 2D NMR spectra allowed for the determination that cycloadducts exist in solution as mixture of the neutral form and dipolar ion. The prepared fused uracils contain both amine and enol functional groups, so share amphiprotic properties and they are zwitterions in solid state. The new class of compounds-amino enols was synthesized, which similarly to amino acids exists as zwitterions. In obtained cycloadducts amino groups and sugar moieties are close each other and they both are in cis configuration and in axial position. It was also shown that different alkenes can be used as dienophiles towards barbituric acid 5-ylidene alditols, for example, styrene or 1-amino-2-thiocarbamoyl-cyclopent-1-ene.

Ion mobility spectrometry (IMS) is a well established technique for the detection of many compounds of interest based on the reduced mobility (K0) values of their ions. While having the advantage of small size, weight, and power, IMS has been subject to low specificity and is subject to interferences that can cause false alarms in detectors used for security applications. The rate of false positive alarms is directly related to the detection window width required to maintain a high rate of true positive detections. These window widths are in turn a result of the historically available accuracy of reference measurements and the range of responses by multiple detectors. The windows cannot be arbitrarily reduced without risking an increase in the rate of false negative responses. Ongoing work has focused on high accuracy calibration as a means of decreasing the false alarm rates by reducing the variability between detectors which would allow for narrower detection windows. Central to the calibration procedure is the selection of an appropriate calibrant (or reference standard) that can be easily characterized and known with a high degree of certainty across a range of instrumental conditions. This review evaluates a number of previously proposed and potential calibrants against seven recommended criteria of suitability. We examine the sources of false positive alarms in IMS-based detectors and propose a calibration procedure based on high accuracy reference measurements. Initial results of applying this procedure in a post-processing manner are promising towards reducing detector variability and detection window width.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

New chiral sulfoxide-1,3-oxazoline ligands have been developed as chiral ligands for Lewis acid-catalyzed asymmetric Diels-Alder reactions. The use of chiral sulfinyl 1,3-oxazoline ligands in copper(II)-catalyzed asymmetric Diels-Alder reactions provided an endo cycloadduct as a major product with moderate enantioselectivity. A rationale is proposed for the mechanism of the asymmetric induction.

The synthesis, electrochemical, optical, and cation sensing properties of a bis(macrocyclic) dye 1, in which the benzo-15-crown-5 and phenylazathia-15- crown-5 subunits are linked through a styryl pyridinium moiety, are reported. In this new ditopic receptor, the benzo-15-crown-5 macrocycle acts as a highly selective binding site for alkaline earth metal cations (MgII and BaII), whereas the phenylazathia-15-crown-5 displays a strong binding affinity towards soft heavy-metal cations (HgII and AgI). The pronounced changes of the absorption and fluorescence spectra of this bichromophoric dye observed upon different metal cation addition make the dye suitable for dual-wavelength analysis and offer an enticing potential for multitasking sensors.
