The title compound, C13H16N2O4, crystallizes in the monoclinic centrosym. space group, P21/c, with four mols. in the asym. unit, thus there is no crystallog. imposed symmetry and it is a racemic mixture The structure consists of a six-membered unsaturated ring bound to a five-membered pyrrolidine-2,5-dione ring N-bound to a six-membered piperidine-2,6-dione ring and thus has the same basic skeleton as thalidomide, except for the six-membered unsaturated ring substituted for the aromatic ring. In the crystal, the mols. are linked into inversion dimers by R22(8) hydrogen bonding involving the N-H group. In addition, there are bifurcated C-H···O interactions involving one of the O atoms on the pyrrolidine-2,5-dione with graph-set notation R12(5). These interactions along with C-H···O interactions involving one of the O atoms on the piperidine-2,6-dione ring link the mols. into a complex three-dimensional array. There is pseudomerohedral twinning present which results from a 180° rotation about the [100] reciprocal lattice direction and with a twin law of 1 0 0 0 [inline formula omitted] 0 0 0 [inline formula omitted] [BASF 0.044 (1)].

Author is Rayner, Peter J.; Burns, Michael J.; Olaru, Alexandra M.; Norcott, Philip; Fekete, Marianna; Green, Gary G. R.; Highton, Louise A. R.; Mewis, Ryan E.; Duckett, Simon B..

Hyperpolarization turns typically weak NMR and MRI responses into strong signals so that ordinarily impractical measurements become possible. The potential to revolutionize anal. NMR and clin. diagnosis through this approach reflect this area’s most compelling outcomes. Methods to optimize the low-cost parahydrogen-based approach signal amplification by reversible exchange with studies on a series of biol. relevant nicotinamides and Me nicotinates are detailed. These procedures involve specific 2H labeling in both the agent and catalyst and achieve polarization lifetimes of ∼2 min with 50% polarization in the case of methyl-4,6-d2-nicotinate. Because a 1.5-T hospital scanner has an effective 1H polarization level of just 0.0005% this strategy should result in compressed detection times for chem. discerning measurements that probe disease. To demonstrate this technique’s generality, the authors exemplify further studies on a range of pyridazine, pyrimidine, pyrazine, and isonicotinamide analogs that feature as building blocks in biochem. and many disease-treating drugs.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 610-09-3, is researched, Molecular C8H12O4, about Fractal to monolayer growth of AgCl and Ag/AgCl nanoparticles on vanadium oxides (VOx) for visible-light photocatalysis, the main research direction is fractal growth halide silver nanoparticle dope vanadium oxide v; visible light photocatalysis.Formula: C8H12O4.

A facile and simple methodol. was adopted for the trapping of highly crystalline AgCl and Ag/AgCl nanoparticles (NPs) into the interlayer spacings of vanadium oxides (VOx). Self-organization of AgCl and Ag/AgCl-NPs on VOx was found to be governed by the nature of the dicarboxylic acids used during the synthesis of the nanocomposites. A “”fractals-like”” morphol. of the AgCl@VOx nanocomposite was achieved in the presence of cis-1,2 cyclohexanedicarboxylic acid. Heating of the AgCl@VOx nanocomposite above 68 °C resulted in the growth of polydispersed and ultrafine (3-4 nm) Ag/AgCl-NPs and its self-organization into monolayer formation on a partly crystalline VOx matrix. Change in the conformation of the dicarboxylic acid to the trans-isomer resulted in the formation of a ‘rod-like’ structure of Ag/AgCl-NPs on a highly crystalline VOx matrix. The band gaps of the nanocomposites were within the range of 1.8 to 2.9 eV. Because of such a low band gap, the synthesized nanocomposites were found to be highly active toward the photooxidation of methylene (MB) and methyl orange (MO) under sunlight.
