Herein we disclosed the use of a remote ‘imidazole’-based precatalyst [(para-cymene)Ru-II(L)Cl](+), C-1 where L=2-(4-substituted-phenyl)-1H-imidazo[4,5-f]([1,10]) phenanthroline) for the selective oxidation of a variety of alkyl arenes/heteroarenes and alcohols to their corresponding aldehydes or ketones in presence of tert-butyl hydroperoxide (TBHP). The remote ‘imidazole’ moiety present in the complex facilitates the activation of oxidant and subsequent generation of active species via the release of para-cymene from C-1, which in-turn was less effective without the ‘imidazole’ moiety. The mechanistic features of C-1 promoted oxidation of alkyl arenes were also assessed from spectroscopic, kinetic, and few control experiments. The substrate scope for C-1 promoted oxidation reaction was assessed based on the selective oxidation of 27-different alkyl arenes/heteroarenes and 25 different alcohols to their corresponding aldehydes/ketones in moderate to good yields.

The steric and electronic drivers of regioselectivity in platinum -catalyzed intramolecular hydroalkoxylation are elucidated. A branch point is found that divides the process between 5-exo and 6-endo selective processes, and enol ethers can be accessed in good yields for both oxygen heterocycles. The main influence arises from an electronic effect, where the alkyne substituent induces a polarization of the alkyne that leads to preferential heteroatom attack at the more electron -deficient carbon. The electronic effects are studied in other contexts, including hydroacyloxylation and hydroamination, and similar trends in directionality are predominant although not uniformly observed.

Catalytic fast pyrolysis (CFP) biocrudes can comprise up to 30 wt % of oxygen content in compounds such as polyphenols, acids, carbonyls, and anhydrosugars and thus require upgrading by, e.g., hydrotreatment, to produce transport fuels. The chemical characterization of phenolic and acidic compounds in biocrudes is of great importance to optimize the CFP process. In this study, an analytical workflow is proposed for nontarget chemical fingerprinting analysis of CFP biocrudes using supercritical fluid chromatography high-resolution mass spectrometry (SFC-HRMS) with negative electrospray ionization (ESI-), followed by multivariate data analysis. The method was developed and tested on five biocrude samples from loblolly pine (Pinus taeda) with varying oxygen content (14.9-28.8 wt % wet basis) due to different CFP conditions. The pixel-based analysis displayed chemical variation between all samples. Twenty-four regions of interest were tentatively identified, including mono- and polyphenols, fatty acids, and methylated and methoxylated phenols. The identification workflow and MS/MS analysis were prioritized on the peaks with the highest relative concentration. The developed SFC-ESI–HRMS method shows high repeatability and analyzed oxygen-containing compounds with hydroxyl and/or carboxyl moieties in combination with other moieties of up to 400 Da.

Zinc oxide-decorated superparamagnetic silica attached to graphene oxide (Fe3O4/SiO2/PTS-GO-ZnO), as a novel nanocomposite, was designed, and its core-shell structure was appropriately characterized by different spectroscopy or microscopy methods and thermal techniques as well as measuring of its porosity and magnetic properties. The catalytic activity of Fe3O4/SiO2/PTSGO-ZnO, as a reusable heterogeneous catalyst, was investigated for efficient one-pot multi-component synthesis of medicinally important functionalized 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-arylnicotinonitrile derivatives. The significant features of the present procedure are mild reaction conditions, low loading of the catalyst, high to quantitative yields of the desired products, avoiding the use of toxic heavy metals or solvents, simple isolation and purification of the products, and stability as well as reusability of the catalyst after at least six consecutive runs.

Lignin is an abundant source of aromatics, and the depolymerization of lignin provides significant potential for producing high-value chemicals. Selective hydrogenolysis of the C-O ether bond in lignin is an important strategy for the production of fuels and chemical feedstocks. In our study, catalytic hydrogenolysis of lignin model compounds (beta-O-4, alpha-O-4 and 4-O-5 model compounds) over Ni3S2-CS catalysts was investigated. Hence, an array of 2D carbon nanostructure Ni3S2-CSs-X-Y derived catalysts were produced using different compositions at different temperatures (X = 0 mg, 0.2 mg, 0.4 mg, 0.6 mg, and 0.8 mg; Y = 600 degrees C, 700 degrees C, 800 degrees C, and 900 degrees C) were prepared and applied for hydrogenolysis of lignin model compounds and depolymerization of alkaline lignin. The highest conversion of lignin model compounds (beta-O-4 model compound) was up to 100% and the yield of the obtained corresponding ethylbenzene and phenol could achieve 92% and 86%, respectively, over the optimal Ni3S2-CSs-0.4-700 catalyst in iPrOH at 260 degrees C without external H-2. The 2D carbon nanostructure catalysts performed a good dispersion on the surface of the carbon nanosheets, which facilitated the cleavage of the lignin ether bonds. The physicochemical characterization studies were carried out by means of XRD, SEM, TEM, H-2-TPR, NH3-TPD, Raman and XPS analyses. Based on the optimal reaction conditions (260 degrees C, 4 h, 2.0 MPa N-2), various model compounds (beta-O-4, alpha-O-4 and 4-O-5 model compounds) could also be effectively hydrotreated to produce the corresponding aromatic products. Furthermore, the optimal Ni3S2-CSs-0.4-700 catalyst could be carried out in the next five consecutive cycle experiments with a slight decrease in the transformation of lignin model compounds.

Three isostructural Zr metal-organic frameworks have been synthesized from (PNP)-N-N-P-N-Ru pincer metallolinkers bearing different combinations of ancillary ligands (1, Zr6O4(OH)(4)(-OAc)(4){cis-((PNP)-N-N-P-N)RuCl2(CO)}(2); 2, Zr6O4(OH)(4)(O2CH)(4)-{ ((PNP)-N-N-P-N)RuCl(CO)(2)}(2)Cl-2; 3, Zr6O4(OH)(4)(OAc)(4){cis-/trans-((PNP)-N-N-P-N)RUCl2(CO)}(2); (PNP)-N-N-P-N = 2,6-(FINPAr2)(2)C5H3N; Ar = p-C6H4CO2-). The structure and composition of the (PNP)-N-N-P-N-Ru pincer MOFs have been determined using synchrotron X-ray powder diffraction, solid- and solution-state NMR spectroscopy, IR spectroscopy, and elemental analysis. Reaction of 2 with (KOBu)-Bu-t results in deprotonation of an NH group of the (PNP)-N-N-P-N-RuCl(CO)(2) linkers. Subsequent treatment with Me3NO removes a Ru-coordinated CO ligand, generating 2-b, which proved to be a recyclable catalyst for the hydrosilylation of aryl aldehydes with Et3SiH. A similar postsynthetic treatment of 1 and 3 does not generate active catalysts, highlighting the importance of precatalyst design and activation. A homogeneous analogue of 2-b also showed inferior catalytic performance, demonstrating the benefit of catalyst immobilization.

The essential oil of wintergreen, which is extracted by steam distillation from Gaultheria genus leaves, is mainly used in aromatherapy. However, due to its adulteration easiness with synthetic material, it is necessary to control samples naturalness with accuracy. The purpose of this work was to develop a methodology to authenticate the essential oil of wintergreen. Wintergreen essential oil is composed of more than 99% methyl salicylate. This aromatic ester can be easily synthesized and used to adulterate wintergreen essential oil. Authentic wintergreen essential oil can be distinguished from adulterated oils by examining their compositions. The detection of methyl salicylate synthetic marker compounds (methyl 4-hydroxybenzoate, dimethyl 4-hydroxyisophthalate or dimethyl 2-hydroxyisophthalate) or the absence of several naturally occurring minor secondary metabolites (ethyl salicylate and vitispirane) contribute to the authentication. Isotopic values of bulk wintergreen essential oil have also been determined using an isotope ratio mass spectrometer (IRMS): the delta C-13 values of authentic samples range from -36.78 to -33.36 parts per thousand, the delta H-2 values range from -173 to -115 parts per thousand and the delta O-18 values range from -1.3 to 5.7 parts per thousand. However, these analytical methods cannot account for the natural variability in the essential oils. To determine the boundaries of the natural isotopic values, C-14 radioactive isotope activity assessment was undertaken, which allows for the determination of the genuineness of samples that are not assessed using multistable isotope approaches. Additional studies evaluating C-14 activity of a noncompliant sample using IRMS identified a C-14-labeled synthetic methyl salicylate adulteration.

The first synthesis of highly strained spirocyclobutane-pyrrolines via a palladium-catalyzed tandem Narasaka-Heck/C(sp(3) or sp(2))-H activation reaction is reported here. The key step in this transformation is the activation of a delta-C-H bond via an in situ generated sigma-alkyl-Pd(II) species to form a five-membered spiro-palladacycle intermediate. The concerted metalation-deprotonation (CMD) process, rate-determining step, and energy barrier of the entire reaction were explored by density functional theory (DFT) calculations. Moreover, a series of control experiments was conducted to probe the rate-determining step and reversibility of the C(sp(3))-H activation step.
