Gold(I) complexes with amine ligands, II. Methylpyridine complexes of gold(I)

Gold(I) complexes of overall formula LAuCl (L = various methylpyridines) are non-conducting in acetone. X-ray structure analyses show that the solid state structure of the corresponding complex 1 (L = 2-picoline) is molecular; the 3-picoline derivative 2 is however ionic (L2Au)+(AuCl2)-. 3-Picoline forms a molecular complex LAuC6F5 (3) and also the ionic (L2Au)+(SbF6)- (4). Complexes 1, 2 and 4 display short Au…Au contacts, leading to chains of gold atoms; additionally, complexes 3 and 4 show weak Au…F contacts. The (3-picoline)-gold(III) complex trans-(L2AuCl2)+(SbF6)- (5) was obtained as a by-product; it too contains short Au…F contacts.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 108-47-4 is helpful to your research. Reference of 108-47-4

The title heteroleptic neutral cobalt(II) tri-tert-butoxysilanethiolate complexes with monodentate nitrogen bases (L) as additional ligands have been prepared by the reactions of [Co{mu-SSi(OtBu)3}{SSi(OtBu) 3}(NH3)]2 (1) with respective bases. For pyridine both types have been prepared – with two (2) or one (3) nitrogen ligand bonded to cobalt(II). [Co{SSi(OtBu)3}2(L)] complexes have been obtained also with 2-picoline (5), 2,4-lutidine (6), 3,5-lutidine (7), and [Co{SSi(OtBu)3}2(L)2] also with N-methylimidazole (8) and morpholine (9). Molecular and crystal structures of the six compounds have been determined by single-crystal X-ray structural analysis. In 3, 5 and 7 three-coordinated cobalt(II) seems to interact very weakly with two oxygen atoms from two Si(OtBu)3 moieties approaching highly distorted trigonal bipyramidal geometry. Compounds 2, 8 and 9 have distorted tetrahedral structures. Both types of complexes gave characteristic electronic spectra, similar within each type.

Iridium-catalyzed C-H borylation of pyridines

The iridium-catalysed C-H borylation is a valuable and attractive method for the preparation of aryl and heteroaryl boronates. However, application of this methodology for the preparation of pyridyl and related azinyl boronates can be challenged by low reactivity and propensity for rapid protodeborylation, particularly for a boronate ester ortho to the azinyl nitrogen. Competition experiments have revealed that the low reactivity is due to inhibition of the active catalyst through coordination of the azinyl nitrogen lone pair at the vacant site on the iridium. This effect can be overcome through the incorporation of a substituent at C-2. Moreover, when this is sufficiently electron-withdrawing protodeborylation is sufficiently slowed to permit isolation and purification of the C-6 boronate ester. Following functionalization, reduction of the directing C-2 substituent provides the product arising from formal ortho borylation of an unhindered pyridine ring.

Enantioselective C-H bond addition of pyridines to alkenes catalyzed by chiral half-sandwich rare-earth complexes

Cationic half-sandwich scandium alkyl complexes bearing monocyclopentadienyl ligands embedded in chiral binaphthyl backbones act as excellent catalysts for the enantioselective C-H bond addition of pyridines to various 1-alkenes, leading to formation of a variety of enantioenriched alkylated pyridine derivatives in high yields and excellent enantioselectivity (up to 98:2 er).

Catalytic addition reactions of alkylazaarenes to vinylsilanes

Strong Br¡ãnsted-base-catalyzed addition reactions of alkylazaarenes with vinylsilanes are reported. The reactions of alkylpyridines and their analogues with vinylsilanes proceed in moderate to high yields in the presence of catalytic amounts of LiTMP, LiCl, and MS 4A. This is a general method that can be applied to catalytic addition reactions of alkylazaarenes with vinylsilanes.

Structural and 1H, 13C, 15N NMR spectroscopic studies of Pd(II) chloride organometallics with 2-phenylpyridine and ammonia, pyridine or its methyl derivatives

Pd(II) chloride organometallics with 2-phenylpyridine and pyridines of general formula [Pd(2ppy?)LCl] (2ppy? = C(2?)-deprotonated form of 2-phenylpyridine (2ppy), acting as N(1),C(2?)-chelating ligand; L = NH3, pyridine, 2-, 3-, 4-methylpyridine, 2,3-, 2,4-, 2,6-, 3,5-dimethylpyridine, 2,4,6-trimethylpyridine) were studied by 1H, 13C and 15N NMR. 1H, 13C and 15N NMR coordination shifts (i.e. differences of chemical shifts for the same atom in the complex and ligand molecules) were discussed in relation to the molecular structures. Single crystal X-ray structure of trans(N,N)-[Pd(2ppy?)(2,4,6col)Cl] was solved. The analysis of 15N NMR coordination shifts for the whole series of the studied organometallics exhibited that all of them had an analogous trans(N,N) geometry.

Flavour and off-flavour compounds of Swiss Gruyere cheese. Evaluation of potent odorants

The flavour of a typical sample of Gruyere cheese and that of a Gruyere exhibiting a potato-like off-flavour was examined by instrumental and sensory analyses. Based on the results of dynamic headspace gas chromatography-mass spectrometry (DHGC/MS), aroma extract dilution analysis (AEDA) and gas chromatography-olfactometry of static headspace samples (GCO-H), 2-/3-methylbutanal, methional, dimethyltrisulphide, phenylacetaldehyde, 2-ethyl-3,5-dimethylpyrazine, 2,3-diethyl-5-methylpyrazine, methanethiol, as well as butyric, 2-/3-methylbutyric and phenylacetic acid form the typical flavour of Gruyere cheese. The potato-like character of the sample showing an aroma defect, however, could not be attributed definitively to one of these compounds. Considering the results of DHGC/MS and AEDA, 2-ethyl-3,5-dimethylpyrazine and 2,3-diethyl-5-methylpyrazine could be the possible causes of the off-flavour.

Synthesis and antiviral activity of a series of HIV-1 protease inhibitors with functionality tethered to the P1 or P1’phenyl substituents: X-ray crystal structure assisted design

By tethering of a polar hydrophilic group to the P1 or P1′ substituent of a Phe-based hydroxyethylene isostere, the antiviral potency of a series of HIV protease inhibitors was improved. The optimum enhancement of anti-HIV activity was observed with the 4-morpholinylethoxy substituent. The substituent effect is consistent with a model derived from inhibitor docked in the crystal structure of the native enzyme. An X-ray crystal structure of the inhibited enzyme determined to 2.25 A verifies the modeling predictions.
