The glaucous appearance of wheat (Triticum aestivum) and barley (Hordeum vulgare) plants, that is the light bluish-gray look of flag leaf, stem, and spike surfaces, results from deposition of cuticular β-diketone wax on their surfaces; this phenotype is associated with high yield, especially under drought conditions. Despite extensive genetic and biochemical characterization, the molecular gene...
The palladium-catalyzed reaction of (hetero)aryl bromides, chlorides, and nonaflates with α-allyl-β-ketoesters provides ready efficient access to functionalized 2,3-dihydrofurans. The reaction tolerates several useful substituents including chloro, fluoro, ether, ketone, ester, cyano, and nitro groups.
New π-conjugated unsymmetrical β-diketones were synthesized thanks to a modular synthetic approach involving in situ generated acylketenes through thermal degradation of 1,4-dioxin-2-ones. This method gave access family new chromophores featuring either an indoline or benzothiazole as electron-donating groups one side and various aromatic moieties the other side. After complexation with boron d...
New complexes of Dy (III) and Gd with b-diketones containing unsaturated aryl substituents were synthesized. Metal polymers based on synthesized obtained by the method radical polymerization. The composition structure metal are established. It is shown that during polymerization coordination environment central ion remains unchanged. spectral-luminescent characteristics compounds studied. pres...
