The addition of organometallic reagents to unsaturated bonds is one of the most powerful tools for carbon-carbon bond formations. Alkylation through organometallic reagents requires stoichiometric quantity of metal and tedious anhydrous operation in most cases. Here, we report umpolung nucleophilic additions of hydrazones to Michael acceptors, carbonyls and imines in water. Under the catalysis of ruthenium(II), the addition reactions could be carried out in pure water to provide various alkylation products in moderate to good yields. (C) 2020 Elsevier Ltd.

Formula: C8H8O2. I found the field of Chemistry very interesting. Saw the article Application of bis(phosphinite) pincer nickel complexes to the catalytic hydrosilylation of aldehydes published in 2021, Reprint Addresses Zhang, J; Chen, XNA (corresponding author), Henan Normal Univ, Sch Chem & Chem Engn, Henan Key Lab Boron Chem & Adv Energy Mat, Xinxiang 453007, Henan, Peoples R China.; Chen, XNA (corresponding author), Zhengzhou Univ, Coll Chem & Mol Engn, Zhengzhou 450001, Peoples R China..

A series of bis(phosphinite) (POCOP) pincer ligated nickel complexes, [2,6-(tBu(2)PO)(2)C6H3]NiX (X = SH, 1; SCH2Ph, 2; SPh, 3; NCS, 4; N-3, 5), were used to catalyse the hydrosilylation of aldehydes. It was found that both complexes 1 and 2 are active in catalysing the hydrosilylation of aldehydes with phenylsilane and complex 1 is comparatively more active. The expected alcohols were isolated in good to excellent yields after basic hydrolysis of the resultant hydrosilylation products. However, no reaction was observed when complex 3 or 4 or 5 was used as the catalyst. The results are consistent with complexes 1 and 2 serving as catalyst precursors, which generate the corresponding nickel hydride complex [2,6-(tBu(2)PO)(2)C6H3]NiH in situ, and the nickel hydride complex is the active species that catalyses this hydrosilylation process. The in situ generation of the nickel hydride species was supported by both experimental results and DFT calculation.

Polymer functionality greatly determines many of the key properties of these materials, such as glass-transition temperature, electrical and thermal conductivity, thermal stability, mechanical strength, and processability. Despite the importance of polymer functionality in determining material properties, the synthesis of functional polymers, with well-defined molecular weights and compositions, can still present a significant challenge, with many of the methods related to pre- or postpolymerization modification lacking synthetic scope, or requiring harsh functionalization conditions or transition-metal coupling reactions to install the desired functionality. Perfluoroaromatic systems are promising for the preparation of novel polymer architectures given that they can be readily functionalized using simple nucleophilic chemistries under very mild basic conditions. While promising, these systems have displayed some drawbacks. Previous work has shown that perfluoroaromatics, such as perfluoropyridine, can demonstrate a high degree of chemical reversibility with heteroatom nucleophiles. If the synthetic potential of these systems is to be realized, then a strategy for the rational design of stable monomers must be developed. Herein, we report the design, synthesis, and characterization of a series of unexplored heteroatom-based ring-opening metathesis polymerization (ROMP)-active monomers containing a reactive perfluoropyridine pendent group, which can be used to readily prepare a wide variety of aryl ether-functionalized polymers, using both pre- and postpolymerization modification strategies. We also establish a direct connection between the dihedral angle of the monomer and its propensity to undergo reversible addition reactions, establishing functional criteria for the design of pre- and postmodifiable systems.

The double functionalization of styrenes through Cu-mediated assisted tandem catalysis was developed. The reaction was initiated by Cu-catalyzed aziridination and the subsequent nucleophilic ring-opening, which was triggered by the addition of (NH4)(2)S2O8 as an oxidant of Cu-catalyst to form a variety of C-C and C-X bonds. The expansion to three contiguous catalytic cycles led to the synthesis of functionalized indolines by one-pot operation.

A three-descriptor quantitative structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R-2 of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R-2 of 0.872 and rms of 0.302 for the test set of 135 compounds. Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.

A single and accessible cationic iridium(III)metallacycle effectively catalyzes the one-pot sequential double hydrosilylation of challenging alpha,beta-unsaturated secondary and tertiary amides to afford, in a controlled and straightforward way, the corresponding reduced products, namely, the related secondary and tertiary amides and amines. The catalytic hydrosilylations of the conjugated amides described herein proceeded in good yields and high chemoselectivities. The critical silyl enolate, in other words silyl ketene aminal intermediate, has been observed and characterized by using control experiments, mass spectrometry and state of the art NMR analyses. The present achievements indicate a promising potential of catalysts based on metallacycles for future significant developments in one-pot multicatalytic synthesis and therefore the production of highly functionalized and complex organic molecules.

Twenty-six Biginelli adducts were synthesized through an ionic liquid-assisted synthesis with up to 92% yield. Sixteen of these Biginelli adducts were then assayed to determine their antiureolytic activity against purified urease from jack beans. The substances BA7-S, BA9-S and BA11-S were shown to be as efficient inhibitors as hydroxyurea, a positive control used in in vitro screening assay against urease. Fluorescence studies revealed that BA7-S, BA9-S, BA11-S and BA5-S possessed high binding constant values of 5.95, 6.72, 4.55, and 4.28 M-1, respectively, while BAS12-S, without substituents, showed a low value of log K-b = 2.16 M-1. In addition, in the most thermodynamically favorable BA5-S and BA7-S urease complexes, the corresponding Biginelli adducts were capable of interacting with the active site of urease through non-ionic interactions, such as hydrophobic interactions, or hydrogen and van der Waals interactions, respectively. In silico studies also supported that the BAs interact with the active site, confirming the fluorescence and kinetic assay studies, which clearly indicate that BA5-S and BA7-S are competitive inhibitors (K-i = 0.96 and 0.57 mM, respectively). In silico studies also showed that the substituents in the aromatic ring interact with Ni atoms to form a stable complex.
