Reductive transformations of easily available oxidized matter are at the heart of synthetic manipulation and chem. valorization. The applications of catalytic hydrofunctionalization benefit from the use of liquid reducing agents and operationally facile setups. Metal-catalyzed hydroborations provide a highly prolific platform for reductive valorizations of stable C:X electrophiles. Here, the authors report an especially facile, broad-scope reduction of various functions including carbonyls, carboxylates, pyridines, carbodiimides, and carbonates under very mild conditions with the inexpensive pre-catalyst Mn(hmds)₂.

Luminescent Eu^III Complexes Immobilized on a Vermiculite Clay Surface was written by Silva, Haryane R.

And the article was included in European Journal of Inorganic Chemistry in 2014.Application In Synthesis of 1-Methyl-1H-imidazol-3-ium chloride This article mentions the following:

Vermiculite clays were leached with HNO₃ and functionalized with (3-chloropropyl)trimethoxysilane. The resulting materials were modified with the methylimidazolium (MID) group to yield cationic surfaces. These materials were characterized by IR spectroscopy, elemental analyses, and sp. surface area. Tetrakis(尾-diketonate)europate(III) complexes, [EuL₄]^– [L = dibenzoylmethane (DBM) and thenoyltrifluoroacetone (TTA)], were immobilized on the vermiculite surface containing the imidazolium cation to yield hybrid surfaces named Vx-MID-EuL₄ (x = 0, 1, and 2), in which x represents the nitric acid concentration in mol L^-1 that was used in the leaching process. The highest luminescence intensities of the intraconfigurational-4f ⁵D₀鈫?sup>7FJ transitions (for which J = 0, 1, 2, 3, and 4) arising from [EuL₄]^– complexes were presented by the hybrid materials containing the amount of imidazolium cation, which depend on the leaching process. The excitation and emission spectra suggested an efficient intramol. energy-transfer process from ligand-to-Eu³⁺ ion in the supported materials. The photoluminescent properties of the hybrid materials were studied based on the emission quantum efficiency (畏), exptl. intensity parameters 惟₂ and 惟₄, and Einstein’s emission coefficient (A_0J). The values of these parameters for the V₂-MID-EuL₄ surface are close to those assigned to the [EuL₄]^– isolated complexes, which indicates that hybrid vermiculite materials are promising red phosphors.

The abnormal activation of JAK2 kinase is closely related to the occurrence and progression of myeloproliferative neoplasms (MPNs). At present, there is still an obvious unmet medical need for selective JAK2 inhibitors in clinic. In this paper, a class of 2-aminopyridine derivatives as potent and selective JAK2 inhibitors was obtained by combining drug design, synthesis and structure-activity relationship studies based on the previously identified lead Crizotinib. Among them, I exhibited high inhibitory activity against JAK2 with an IC₅₀ of 9 9 nmol/L, moreover, it showed 276- and 184-fold selectivity over JAK1 and JAK3, resp. Besides, I had a significant antiproliferative activity against HEL cells, and also inhibited the phosphorylation of JAK2 and its down-stream signaling pathway. These results indicated that 2-aminopyridine compound I had the potential to be developed as a selective JAK2 inhibitor for further study. In the experiment, the researchers used many compounds, for example, 4-Bromo-1-methylimidazole (cas: 25676-75-9Recommanded Product: 25676-75-9).

Previously disclosed dihydropyrazolopyrimidines are potent and selective blockers of I_Kur current. A potential liability with this chemotype is the formation of a reactive metabolite which demonstrated covalent binding to protein in vitro.
