Asymmetric Total Synthesis and Biosynthetic Implications of Perovskones, Hydrangenone, and Hydrangenone B

Perovskones and hydrangenones are a family of structurally complex triterpenoids that were mainly isolated from the genus Salvia medicinal plants. These isoprenoids exhibit a broad range of biological activities, such as antitumor and antiplasmodial activities. Here, we report the collective total synthesis of perovskone, perovskones C, D, F, hydrangenone, and hydrangenone B. The key strategies in this work include the following: (1) an asymmetric photoenolization/Diels-Alder reaction was developed to construct a tricyclic ring bearing three contiguous quaternary centers, which was used to build the core icetexane skeleton; (2) a bioinspired Diels-Alder reaction of perovskatone D with trans-α-ocimene was applied to stereospecifically generate perovskones; (3) late-stage oxidations and ring forming steps were developed to synthesize perovskones and hydrangenones. Our synthetic work suggests that (1) perovskatone D may serve as the precursor of the biosynthesis of perovskones and (2) the formation of hydrangenone and hydrangenone B, containing a five-membered D ring, may involve an oxidative ring cleavage and ring regeneration process.

AgCuO2 as a novel bifunctional electrocatalyst for overall water splitting in alkaline media

Nanostructured transition metal oxides are among the most prevalent catalysts for the water-splitting process. Herein, AgCuO2 nanoparticles (NPs) are introduced as a novel bifunctional electrocatalyst for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline media. The catalyst, AgCuO2 NPs, exhibited excellent electrocatalytic activity together with a low overpotential for the overall water-splitting process. The AgCuO2 exhibits excellent electrocatalytic activity with a low onset overpotential of 29 mV for the HER and the onset overpotential of 360 mV for the OER, with superior long-term stability in 1.0 M KOH. The catalyst delivered 10 and 100 mA cm?2 at extremely low overpotentials of 42 and 47 mV for the HER and 10 mA cm?2 at an overpotential of 388 mV for the OER. This work suggests an important reference toward the use of novel bimetallic oxides as highly active and stable bifunctional electrocatalysts for high-performance water splitting.

Coordination chemistry of Cu(II), Co(II), Zn(II) and Ag(I) complexes of isomeric pyridine 2- and 4-carboxamides and their biological activity evaluation

Eight complexes of Cu(II), Co(II), Zn(II) and Ag(I) with rarely studied ligands, N,N-diisopropyl/butylpicolinamide (L1/L2), and N,N-diisopropyl/butylisonicotinamide (L3/L4), have been synthesized and characterized spectroscopically, and their molecular and crystal structures have been reported. Diverse coordination modes of these positional isomers have been discovered, discussed and compared with the limited available literature in light of their respective convergent and divergent nature. All the complexes show stable and extended 1D, 2D or 3D coordination/H-bonded networks owing to a large number of weak C–H?O/X and other intermolecular interactions. Further, the ligands as well as the metal complexes have been evaluated for their antimicrobial activity and have turned out to be potent antimicrobial agents.

Stabilized alkaline Fe(VI) charge transfer

Superiron cathodes, consisting of unusual Fe(VI) particles, are substantially stabilized with a low-level zirconia coating, which improves the experimental energy storage capacity of alkaline superiron batteries. Fe(VI) cathodes sustain three-electron alkaline reduction at a single, energetic [0.60 V vs standard hydrogen electrode (SHE)] potential. Superiron cathode salts such as K2 FeO4 and Cs2 FeO4 are stable in the solid state but tend to be passivated in alkaline electrolyte due to the formation of an Fe(III) overlayer. A zirconia coating is derived from ZrCl4 through an organic medium by the conversion of ZrCl4 to ZrO2. The zirconia coating shuttles hydroxide through to the interior cathode material, sustains a high rate of alkaline cathode charge transfer in the redox reduction of Fe(VI) to Fe(III) redox reduction, and inhibits Fe(III) passivation. The zirconia coating effectively enhances the stability of these superiron cathodes. However, for an Fe(VI) salt, which is not stable in the solid state, such as BaFeO2, an applied zirconia coating is not observed to stabilize alkaline cathodic charge transfer. Small particle and solid KOH and AgO additives each are observed to improve Fe(VI) cathodic charge transfer and enhance accessible Fe(VI) gravimetric capacity.

The super-iron boride battery

A high-capacity alkaline redox storage chemistry is explored based on an environmentally benign zirconia-stabilized Fe6+ B2- chemistry. This super-iron boride battery sustains an electrochemical potential matched to the pervasive, conventional MnO2 -Zn battery chemistry, but with a much higher electrochemical storage capacity. Whereas a conventional alkaline battery pairs the 2 e- zinc anode with a 1 e- MnO2 cathode, the new alkaline cell couples an 11 e- boride anode, such as VB2, with a 3 e- storage hexavalent iron cathode. The cell has an open circuit and discharge potential comparable to the conventional, commercial alkaline battery. Based on VB2 (72.6 g mol-1) and the Fe(VI) salt K2 FeO4 (198.0 g mol-1), the super-iron boride cell has an 11 Faraday theoretical capacity of 369 mAh g-1. Added AgO mediates and further facilitates the 3 e- K2 FeO4 reductive charge transfer, and we demonstrate for super-iron boride that over 300 mAh g-1 is approached experimentally, which is substantially higher than the conventional Zn MnO2 alkaline battery with an experimental capacity (to 0.8 V) of 160 mAh g-1 and a theoretical capacity of 224 mAh g-1.

Room temperature solid-state transformation from Ag2Cu 2O3 to Ag2Cu2O4 by ozone oxidation

Thermal decomposition of metal nitrates in air and hydrogen environments

The decomposition of metal nitrates in air has been systematically studied by thermogravimetry. Observed temperature of decomposition (Td) have been inversely correlated to the charge densities (CD) of the metal cations. Due to a back-donation of electronic cloud from the nitrate to an unfilled d-orbital of transition and noble metals, their nitrates generally exhibited lower TdS ( 850 K). The thermal stability/reducibility of metal nitrates in an hydrogen atmosphere has also been studied by temperature-programmed reduction (TPR). Observed reduction temperatures (Tr) for nitrates of the base metals and the noble metals are lower than their Td, i.e., Tr d. The lowering of Tr might be attributed to a spillover of hydrogen to a nitrate moiety through heterolytic (ionic) and homolytic (atomic) dissociation of hydrogen on the respective base and noble metals. The stoichiometry of hydrogen consumption, quantitatively measured from TPR, varied with the group of metal cations. According to the stoichiometry, the end product in the TPR reduction was NH3 (NH2/NNO3-a??4.4) and N2 (NH2/NNO3-a??2.4) for nitrates of the noble and base metals, respectively. The Trs for nitrates of the transition metals are often a??20 K higher than their Tds, and the ratio NH(2)/NNO3- varies widely between 0.7 and 3.2. Their reduction may be triggered by thermal decomposition.

Silver mediation of Fe(VI) charge transfer: Activation of the K2FeO4 super-iron cathode

An unexpectedly large Ag(II) mediation of Fe(VI) redox chemistry improves alkaline Fe(VI) cathodic charge transfer. Combined with a Zn anode, this results in a cell with 3- to 5-fold higher energy capacity than the conventional high-power Zn/MnO2 alkaline battery, and twice that previously observed for Zn/BaFeO4. Both experimental results and a model of this phenomenon are presented. The Ag(II) salt may be introduced as a simple composite of AgO with the Fe(VI) salt. The Fe(VI) super-iron salt K2FeO4 has a high 3e- intrinsic charge capacity (406 mA/g), and is more environmentally benign than the Fe(VI) salt BaFeO4, but had exhibited comparatively poor charge transfer. Successful AgO cathodic activation of both K2FeO4 and BaFeO4 redox chemistry are presented. Various other K2FeO4 activators are also studied. An observed interaction of Fe(VI) with Mn(VII/VI) can improve charge efficiency of a K2FeO4 composite with KMnO4 or BaMnO4, albeit not to the extent observed in an K2FeO4/AgO composite cathode. The extent of an activation effect of oxides, hydroxides, and titanates salts, as well as KMnO4, BaMnO4, AgMnO4, and fluorinated graphites, on the cathodic discharge of K2FeO4 are probed.

AgO investigated by photoelectron spectroscopy: Evidence for mixed valence

We present photoelectron spectroscopy investigations of in-situ prepared AgO. The sample was prepared by room temperature oxidation of Ag in an electron cyclotron resonance O2 plasma. In contrast to other measurements based on ex situ prepared AgO powder samples, our investigations show a distinct double peak structure of the O 1s signal with a remarkable chemical shift of 2.9 eV between the two O 1s components. These two components can not be motivated from a crystallographic point of view as the oxygen sites are all equivalent in the unit cell. We interpret this double peak structure as a characteristic feature of AgO and discuss it in terms of mixed valences.
