Intramolecular monomer-on-monomer (MoM) Mitsunobu cyclization for the synthesis of benzofused thiadiazepine-dioxides

The utilization of a monomer-on-monomer (MoM) intramolecular Mitsunobu cyclization reaction employing norbornenyl-tagged (Nb-tagged) reagents is reported for the synthesis of benzofused thiadiazepine-dioxides. Facile purification was achieved via ring-opening metathesis (ROM) polymerization initiated by one of three metathesis catalyst methods: (i) free metathesis catalyst, (ii) surface-initiated catalyst-armed silica, or (iii) surface-initiated catalyst-armed Co/C magnetic nanoparticles.

Mechanism of carbon-nitrogen bond scission on unsupported transition metal sulfides

The reactivity of a series of amines with various structures and different numbers of hydrogen atoms on the carbon atoms in the alpha and beta position, with respect to the nitrogen atom, was examined on four transition metal sulfides, i.e. NbS3, MoS2, RuS2, and Rh2S3. It is shown that the reaction mechanism proceeds via an elimination or a nucleophilic substitution the relative importance of which depends on the structure of the substrate to be transformed and on the transition metal sulfides properties. NbS3 is the most active sulfide of the series for the elimination reaction due to its high acidity, but it is inactive for the nucleophilic substitution. On the other hand, the surface species of Rh2S3 can be involved in a nucleophilic substitution but not in an elimination reaction. The other sulfides of the series behave in between. These results clearly demonstrate that the catalysts intervene differently in the HDN mechanism. Moreover, for a given solid the structure of a nitrogen-containing molecule strongly affects the elementary steps of its transformation. Accordingly, a precise mechanistic study of the reactivity of a model molecule at the surface of a sulfide cannot be generalized to the overall HDN process which involves several types of molecules.

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.Product Details of 10049-08-8, you can also check out more blogs about10049-08-8

An unexpected formation of a Ru(III) benzylidene complex during activation of a LatMet-type ring-opening polymerisation catalyst

Upon activation with C2Cl6 known latent Ru metathesis catalyst LatMet (13) exhibited activity in RCM and in ROMP of DCPD. A by-product of such activation, an aryloxybenzylidene ruthenium(III) complex 17 have been independently synthesised by reacting 13 with C2Cl6. This unique complex was characterised by spectroscopic and electrochemical methods, and by X-ray crystallography. To the best to our knowledge, this is the first isolated and structurally determined Ru(III) alkylidene complex reported.

One-pot synthesis of hydrous MnO2 nanowires for selective oxidative transformation of furfuryl alcohol

Hydrous MnO2 nanowires were easily synthesized by an one-pot synthesis with a simple hydrothermal method. As prepared hydrous MnO2 nanowires were characterized with scanning emission microscopy (SEM), transmit emission microscopy (TEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET). They showed a good catalytic activity with the suitable nano-size of 4-5 nm and morphology. The furfuryl alcohol was selected as a substrate and the reaction was carried out in a toluene solvent at 100 ? under the atmospheric pressure of oxygen. The hydrous MnO2 nanowire catalyst exhibited an excellent yield of furfural with the first-rate selectivity and conversion. The catalytic performance during recycle tests was also carried out and the catalyst showed a good mechanical strength with a negligible loss in the activity over five reaction cycles.

The effect of material purity on the optical and scintillation properties of solution-grown trans-stilbene crystals

Large, 10 cm-size, single crystals of trans-stilbene were grown for the first time from solution by a temperature reduction technique. Their scintillation performance for fast neutron detection depended on the purity of the initial starting material. A light-yield-inhibitor-free starting material was specially synthesized and crystals from this material were compared to those grown from commercially available powders of trans-stilbene. The use of pure material made possible the growth of the large size crystals (>400 g) with excellent neutron-gamma discrimination performance, which are needed for use as a radiation detection material.

Synthesis of 2,3,4,7-tetrahydro-1H-azepines as privileged ligand scaffolds for the design of aspartic protease inhibitors via a ring-closing metathesis approach

We have developed a short and highly efficient synthetic strategy towards the hitherto hardly known 3,5- and 3,6-disubstituted 2,3,4,7-tetrahydro-1H-azepine scaffold via a ring-closing metathesis approach utilizing inexpensive and readily available starting material such as methyl acrylate and allylamine. Both seven-membered azacycle scaffolds bearing suitable functional groups, which can easily be modified by means of standard synthetic chemistry, serve as non-peptidic heterocyclic core structures for the further design and synthesis of aspartic protease inhibitors. Through specific decoration with appropriate side chains, individual inhibitors can be tailored with respect to selectivity towards particular family members. A first generation of this class of non-peptidic inhibitors have been tested against the aspartic proteases Plasmepsin II and HIV-I protease, respectively, showing promising activity as well as selectivity with IC50 values in the micromolar range.

Olefin metathesis transformations in thermomorphic multicomponent solvent systems

Homogeneous catalysis is a major actor of modern chemistry with a growing impact on clean and sustainable chemical processes. However, for many industrial applications of homogeneously catalyzed reactions, an easy separation and recovery of the catalyst should be guaranteed. Temperature-dependent multicomponent solvent (TMS) systems have been evaluated in ruthenium catalyzed olefin metathesis transformations. Propylene carbonate was found a suitable solvent for the ruthenium catalyzed ring-closing and cross-metathesis transformations of a variety of substrates including renewable fatty esters. The potential of a TMS system consisting of propylene carbonate/ethyl acetate/cyclohexane was then evaluated in the cross-metathesis of the renewable methyl 10-undecenoate with methyl acrylate and acrylonitrile.
