Ruthenium nanoparticles supported on titania are over three times more active than conventional ruthenium on carbon for the hydrogenation of lactic acid. This superior catalytic activity can be due to a combined action of small ruthenium nanoparticles and the titania support.

Here we report the development of a straightforward synthetic procedure for the preparation of spirocyclic endoperoxides as synthetic analogues of the natural product dihydroplakortin. The peroxides presented here are more potent antiplasmodials than dihydroplakortin itself and we proved for the first time their antimalarial activity in vivo. This journal is

(Graph Presented) Optically active new 4-hydroxy-N-(2-hydroxyethyl)butanamides are reported. The structure in the solid state of four racemic mixtures and three enantiomeric pure compounds was determined by X-ray diffraction. The solid state arrangements of enantiomerically pure compounds were compared with those of their racemic mixtures. The butanamides prefer lineal conformations in the solid state. They form dimers and polymers through intermolecular hydrogen bonds. Variable temperature 1H NMR experiments were performed in order to analyse the strength of the hydrogen bonds in the neutral molecules in solution. The pKa values of the dihydroxybutanamides in DMSO determined by cyclic voltammetric (11.1-14.5) were lower than those reported for amides RNHCOR without hydroxyl groups (25.9). The latter motivated us to investigate the role of hydrogen bonds in the stabilization of the corresponding anions and in consequence in the acidity of the amides. The explanation of the enhanced N – H acidity of dihydroxybutanamides was found in the cyclic voltammetric experiments, in conductimetric titrations using nBu4NOH in methanol and titration with CsOH in acetonitrile. The optimised structures for the neutral molecules and their mono and dianions calculated by ab-initio HF(6-31 + G?) and B3LYP(6-31 + G?) methods supported the explanation of the enhanced N – H acidity.

The collisional activation (CA) and charge stripping (CS) mass spectra of the three +. isomers, allene, propyne and cyclopropene, are reported.The extent of isomerization among these ions prior to collisional excitation depends on their internal energy content, but is small.Each +. ion structure also can uniquely be generated via appropriate dissociative ionizations.Analysis of mixtures of +. (daughter) ion structures is, in general, not possible from CA and CS mass spectra alone but may be aided by appearance energy measurements.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Safety of 3-Methyldihydrofuran-2(3H)-one. Introducing a new discovery about 1679-47-6, Name is 3-Methyldihydrofuran-2(3H)-one

Cyclopentenones are synthetically versatile structures, and their straightforward construction from alkynone substrates by employing synthetically streamlining C-H insertion is conceptually appealing and of high synthetic potential. But, its implementation is very limited. Herein we report a Au-catalyzed version, which affords 2-bromocyclopent-2-en-1-ones with a broad scope and synthetically desirable diastereoselectivities. The proposed key intermediate capable of the observed insertion into unactivated C-H bonds is a fully functionalized gold vinylidene, which is generated via a novel intermolecular strategy. This flexible access of likely gold vinylidenes opens various opportunities to explore their versatile reactivities.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 3-Methyldihydrofuran-2(3H)-one, you can also check out more blogs about1679-47-6

Rate constants have been determined by steady-state EPR spectroscopy experiments for hydrogen-atom abstraction by ButO radical from a variety of esters.The values, which range over two orders of magnitude (5 * 103-5 * 105 dm3 mol-1 s-1 at ca. 300 K) are significantly lower than those for related ketones and ethers and reflect, at least in part, the importance of the appropriate C-H bond dissociation energies and the stabilization of carbonyl-conjugated radicals.The relative lack of reactivity of C-H bonds in unsubstituted five-membered rings is believed to reflect ring-strain in the derived radicals; possible stereoelectronic effects are discussed.

A strategy directed toward the synthesis of the highly functionalized trichothecene anguidine (1) is detailed. The route entails several challenges. The first of these is the synthesis of the congested, achiral cyclopentadienyl malondialdehyde 8, which is induced to undergo a highly diastereoselective, but modestly enantioselective, carbonyl ene reaction to give hydroxy aldehyde 7 under the influence of europium catalysts. The cyclopentadiene ring of 22d is transformed into the bis(allyloxy) epoxide functionality of 33c, which cyclizes regioselectively with ZnBr2 to the tetracycle 35. A new method using (Ph3P)4RhH for the deprotection of the allyl ethers is described. Selective functionalization of the C3, C4, and C12 hydroxyl groups of triol 40a can be accomplished, but somerization of the exocyclic olefin of tetraacetate 48b gives the Delta8,9 olefin 49 and not the desired Delta9,10 olefin 50.

Reference of 1679-47-6, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1679-47-6, 3-Methyldihydrofuran-2(3H)-one, introducing its new discovery.

Eight defined primary and secondary alkylhydroperoxides were decomposed in n-alkanes as the solvent, mostly in the presence of manganese stearate.In all cases the corresponding alcohols and carbonyl compounds were formed as the main products with yields of 60-90percent.Besides, difunctional products were formed by an intramolecular H-transfer in the alkoxy radicals corresponding to the starting hydroperoxides.Products possibly formed by an intramolecular H-transfer in the corresponding alkylperoxy radical could be found only in the case of 4-methyl-2-hydroperoxy pentane.The amount of products formed by intramolecular H-transfer depended on the nature of the C-H bond in delta-position to the original hydroperoxy group and lay between 4percent (primary C-H in the case of 4-hydroperoxy heptane) and 13percent (tertiary C-H in the case of 2-hydroperoxy-5-methyl hexane) with respect to the starting hydroperoxide.The amount of products formed by oxidative attack of the alkoxy and alkylperoxy radicals at the normal paraffins used as the solvents was unexpectedly low (always less than 10percent with respect to the starting hydroperoxide).An increment system is proposed for the calculation of 13C-nmr shifts in alkyl hydroperoxides.
