Fuchise, Keita published the artcileOrganocatalytic ring-opening polymerization of cyclotrisiloxanes using silanols as initiators for the precise synthesis of asymmetric linear polysiloxanes, Synthetic Route of 597-52-4, the publication is Polymer Chemistry (2020), 11(48), 7625-7636, database is CAplus.

The organo-catalytic controlled/living ring-opening polymerization (ROP) of cyclotrisiloxanes such as hexamethylcyclotrisiloxane (D3) and 1,3,5-trimethyl-1,3,5-trivinylcyclotrisiloxane (V3) using silanol initiators and guanidine catalysts produced various asym. linear poly(dimethylsiloxane) (PDMS) and poly[methyl(vinyl)siloxane] (PMVS) compounds with controlled number-average molar mass (Mn), narrow molar-mass dispersity, and well-defined terminal structures. An extensive range of solvents and catalysts were tested in order to optimize the conditions for the ROP of D3 and V3 as well as to minimize undesired side-reactions, particularly the condensation of two Si-OH groups. 1,3-Trimethylene-2-n-propylguanidine (TMnPG) and 1,3-trimethylene-2-ethylguanidine (TMEG) were identified as the most appropriate catalysts for the ROP of D3 and V3. Asym. linear polysiloxanes that contain either a functional group on one terminus, i.e., hemi-telechelic polysiloxanes, or two different functional groups on each terminus, i.e., heterotelechelic polysiloxanes, were conveniently obtained from choosing a suitable combination of a functionalized silanol initiator and a functionalized chlorosilane end-capping agent. The controlled synthesis of a PDMS/PMVS diblock copolymer was also achieved by consecutive copolymerizations of D3 and V3. These polymerizations are considered to proceed via the initiator/chain-end activation mechanism, and intensive removal of water from the starting materials is necessary to control the polymerizations

Ido, Yohei published the artcileA Reactor System Using Electrospray in the Liquid Phase and Its Application in Selective Cyclosiloxane Synthesis, Quality Control of 597-52-4, the publication is Industrial & Engineering Chemistry Research (2017), 56(16), 4878-4882, database is CAplus.

Electrospraying is an electrochem. technique in which fine droplets are generated in the balance of electrostatic repulsion and surface tension. In this paper, we applied electrospray in the liquid phase in a new reactor system in which pos. and neg. charged fine droplets collided with each other between two electrospray nozzles submerged in a solvent. When the hydrolysis of alkylchlorosilanes was carried out using this reactor, not only did the reaction rates increase, but also, the product distribution changed: the kinetically favored cyclotrimer was predominantly formed over the thermodynamically favored cyclotetramer. The yield of cyclotrimer increased with an increase in the voltage between the needles. Since the droplet size decreases with an increase in the applied voltage, the result suggests that the formed cyclotrimer could diffuse into the solvent before it was converted to the thermodynamically favored cyclotetramer.

Metal nanoparticles were formed on graphene oxide by a deposition process with hydrosilane, giving thin layer metal-graphene oxide (metal/GO) composites. The particle size and catalytic activity could be controlled by varying the hydrosilane amount Hydrosilane prevented the aggregation of GO layers by surface functionalization via silane coupling reaction. The metal/GO composites were evaluated as catalysts in hydrosilane oxidation

A new process for simultaneously obtaining two chem. building blocks, MeOH and silanol, was realized starting from silyl formates which can be derived from silane and CO₂. Understanding the reaction mechanism enabled the authors to improve the reaction efficiency by the addition of a small amount of MeOH.

Manna, Cesar M. published the artcileStereoselective Catalysis Achieved through in Situ Desymmetrization of an Achiral Iron Catalyst Precursor, Synthetic Route of 597-52-4, the publication is Journal of the American Chemical Society (2015), 137(45), 14232-14235, database is CAplus and MEDLINE.

Stereoselective catalysis proceeds with catalyst control but without the need to synthesize preformed chiral catalysts or ligands. Fe-based catalysts were discovered to effect the stereoselective polymerization of lactides starting from a single achiral precursor and the proper choice of an achiral silanol additive. Spectroscopic anal. of the polymer revealed that the stereoselectivity originates from an enantiomorphic site rather than a chain end stereocontrol mechanism. Fe intermediates that are stereogenic at Fe probably form in situ as a result of desymmetrization that occurs from a change in the metal coordination number The proposed mechanism is supported by a combination of spectroscopic measurements, model complexes, kinetic measurements, and DFT calculations

Nojima, Susumu published the artcileSelective Oxidation with Aqueous Hydrogen Peroxide by [PO₄{WO(O₂)₂}₄]^3- Supported on Zinc-Modified Tin Dioxide, Computed Properties of 597-52-4, the publication is ChemCatChem (2015), 7(7), 1097-1104, database is CAplus.

The supported phosphorus-containing tetranuclear peroxotungstate ([PO₄{WO(O₂)₂}₄]^3-, denoted by PW4) catalysts by using zinc-modified SnO₂ supports with different zinc contents [PW₄-Zn(x)/SnO₂, in which x denotes the zinc content (wt%)] were prepared The supported catalysts, in particular PW4-Zn(0.8)/SnO₂, could act as efficient and reusable heterogeneous catalysts for selective oxidation with aqueous H₂O₂ as the terminal oxidant. The catalytic performance of PW4-Zn(0.8)/SnO₂ was much superior to those of the corresponding homogeneous analog THA₃PW4 (THA = tetra-n-hexylammonium) and the previously reported tungstate-based heterogeneous catalysts such as our W-Zn/SnO₂. In the presence of PW4-Zn(0.8)/SnO₂, various types of organic substrates such as alkenes, amines, silanes, and sulfides could be converted into the corresponding oxygenated products in high to excellent yields by using near-stoichiometric amounts of H₂O₂ with respect to the substrates (typically 1.2 equivalent). The PW4 species interacting with highly dispersed Zn²⁺ species on SnO₂ likely plays an important role in the present oxidation

Oxidation of triethylsilane, tert-butyldimethylsilane, dimethylphenylsilane, triphenylsilane, 1,1,1,2-tetramethyl-2-phenyldisilane, tris(trimethylsilyl)silane, hexamethyldisilane, tetrakis(trimethylsilyl)silane, 1,1,3,3-tetraisopropyldisiloxane with chlorine dioxide was carried out. The reaction products of studied triorganosilanes with chlorine dioxide in an acetonitrile solution were the corresponding silanols and siloxanes. A mechanism explaining the formation of products and the observed regularities of the oxidation of silanes with chlorine dioxide has been proposed. A thermochem. anal. of some possible pathways in the gas phase using methods G4, G3, M05, and in an acetonitrile solution by the SMD-M05 method was carried out. The oxidation process can occur both with the participation of ionic and radical intermediates, depending on the structure of the oxidized substrate and medium.

Hill, Michael S. published the artcileSingle-source AACVD of composite cobalt-silicon oxide thin films, Category: alcohols-buliding-blocks, the publication is Inorganica Chimica Acta (2014), 47-56, database is CAplus.

A series of cobalt(II) complexes comprising either triorganosiloxide or tris(tert-butoxy)siloxide ligands were synthesized and characterized. A mononuclear constitution is enforced through the incorporation of bi- and tridentate N-donor ligands. The resultant 4- or 6-coordinate complexes were identified by single-crystal x-ray diffraction anal. and were assessed for their potential as mol. precursors to hybrid cobalt/silicon oxide thin film materials by TGA. A TMEDA adduct of the bis-ligated Co(II) tris(tert-butoxy)siloxide species was used as a single-source precursor for the AACVD of aesthetically attractive blue composite films. Anal. by PXRD, SEM, EDS and XPS indicated the production of amorphous, continuous films with the bulk compositions reflecting the cobalt, silicon and oxygen stoichiometry of the mol. precursor complex.

Visible-light-promoted hydrolysis of hydrosilanes catalyzed by iodo[meso-tetrakis(4-methoxyphenyl)porphyrinato]rhodium [(TAP)Rh-I] to produce silanols and dihydrogen efficiently under mild conditions was reported. (TAP)Rh-H was observed as the key intermediate through stoichiometric activation of the Si-H bond by (TAP)Rh-I. Addition of water drove the stoichiometric activation of Si-H into catalysis.
