We have examined enantioselective bioreduction of acetophenone and its substituted derivatives into corresponding S-alcohols catalyzed by Daucus carota and Petroselinum crispum plant cells in water and isooctane. We found that the nature of the substituent has a profound effect on the relative reactivity of substituted acetophenones and enantioselectivity of biocatalytic reduction. Electron-withdrawing substituents -Br and -NO2 enhance the initial rate of reaction and yields of products, while electron donating substituent -OCH3 decreases them. The reduction rates and yields of products in water were noticeably higher in comparison with similar reductions conducted in isooctane. Correlations between the initial reaction rate and the substituent constant (sigma(+)) in the aromatic ring characterizing its nature were established. Comparison of rho constants of bioreduction catalyzed by D. carota and P. crispum shows that the sensitivity of the reduction to the nature of the substituents is more significant in the case of D. carota biocatalyst. Comparison of rho constants for D. carota and P. crispum in water and isooctane indicates that the sensitivity of bioreduction to the nature of the substituent tends to increase from water to isooctane.

A novel and rapid approach to characterise the occurrence of contaminants of emerging concern (CECs) in river water is presented using multi-residue targeted analysis and machine learning-assisted in silico suspect screening of passive sampler extracts. Passive samplers (Chemcatcher (R)) configured with hydrophilic-lipophilic balanced (HLB) sorbents were deployed in the Central London region of the tidal River Thames (UK) catchment in winter and summer campaigns in 2018 and 2019. Extracts were analysed by; (a) a rapid 5.5 min direct injection targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for 164 CECs and (b) a full-scan LC coupled to quadrupole time of flight mass spectrometry (QTOF-MS) method using data-independent acquisition over 15 min. From targeted analysis of grab water samples, a total of 33 pharmaceuticals, illicit drugs, drug metabolites, personal care products and pesticides (including several EU Watch-List chemicals) were identified, and mean concentrations determined at 40 +/- 37 ng L-1. For targeted analysis of passive sampler extracts, 65 unique compounds were detected with differences observed between summer and winter campaigns. For suspect screening, 59 additional compounds were shortlisted based on mass spectral database matching, followed by machine learning-assisted retention time prediction. Many of these included additional pharmaceuticals and pesticides, but also new metabolites and industrial chemicals. The novelty in this approach lies in the convenience of using passive samplers together with machine learning-assisted chemical analysis methods for rapid, time-integrated catchment monitoring of CECs.

This paper describes the synthesis, structure, and reactivity of (eta(5)-C5Me5)(2)U(=-P-2,4,6-(Pr3C6H2)-Pr-i)(OPPh3) (2). Compound 2 can be accessed by a salt metathesis reaction of the uranium methyl chloride metallocene (eta(5)-C5Me5)(2)U(Cl)Me (1) with 2,4,6-(Pr3C6H2PHK)-Pr-i in toluene in the presence of Ph3PO at ambient temperature. Furthermore, it reacts as a masked synthon for the divalent uranium fragment (eta(5)-C5Me5)(2)U by elimination of the phosphinidene fragment (2,4,6-(Pr3C6H2P)-Pr-i:) on exposure to small organic molecules such as Ph2S2, Ph2Se2, bipy, ketazines, carbodiimides, diazenes, and organic azides. Nevertheless, it also forms carbodithioates, imido, diiminatos, and metallaaziridines when it is treated with isothiocyanate, nitrites, and isonitriles, respectively. In contrast, after addition of Me,SiN 3 the uranium azido species (eta(5)-C5Me5)(2)U[N(SiMe3)P(2-NHCMe2-4,6-(Pr2C6H2)-Pr-i)N(SiMe3)]-(N-3) (13) is isolated in good yield.

Porous nanoreactors demonstrate immense potential for applications in heterogeneous catalysis due to their excellent mass-transfer performance and stability. The design of a simple, universal strategy for fabricating nanoreactor catalysts is of significance for organic transformation. In this study, a nanoreactor with a hierarchical mesoporous yolk-shell structure was successfully prepared by the high-temperature carbonization of a ZIF-67@polymer composite. The core of the resultant Co@ZDC@mC material comprised Co NPs anchored in the ZIF-67-derived carbon framework, while the shell comprised resin-polymer-derived mesoporous carbon. The as-obtained Co@ZDC@mC-700 catalyst enriched reactants, efficiently catalyzed the reaction in the core, and permitted the desorption of the product from the nanoreactor. In the catalytic reduction of nitrobenzene with N2H4.H2O, Co@ZDC@mC-700 exhibited superior catalytic efficiency (TOF=1136.3 h(-1)). In addition, Co@ZDC@mC-700 exhibited excellent performance for the catalytic reduction of various functionalized nitroarenes, as well as good reusability and recyclability. Hence, a simple, useful approach for fabricating a metal-organic-framework-derived non-noble metal-based yolk-shell nanoreactor for effective catalytic transformation is proposed.

A convenient one-pot synthesis of allylsilanes from enolizable methyl aryl ketones has been developed. The first step involves nucleophilic addition of the trimethylsilylmethyl group to ketones using the alkylation method developed by Ishihara with slight modification to generate the corresponding beta-silylalkoxides. The second step entails addition of diisobutylaluminum chloride and heating at about 130 degrees C overnight to afford allylsilanes in fair yields.

A new Fe(II) Schiff base complex anchored on mont-K10 (Fe@imine-mont-K10) was synthesized and extensively characterized by FTIR, powder X-ray diffraction, SEM-EDX, TEM, ESR, X-ray photoelectron spectroscopy (XPS), BET surface area measurement, solid state Si-29 NMR and ICP-AES analysis. The catalytic activity of the complex was investigated for hydrogenation of ketones. The results indicated that it exhibited good catalytic activity for hydrogenation of aromatic as well as aliphatic ketones in i-PrOH/CH3CN (1:1) using Na-i-OPr as base at 80 degrees C resulting in moderate to excellent isolated yields (51-99%) of their corresponding products.
