The ring opening polymerization (ROP) of 1,3,5-trihexyl-1,3,5-trimethylcyclotrisiloxane (D⁶₃) and 1,3,5-triheptyl-1,3,5-trimethylcyclotrisiloxane (D⁷₃) was promoted by acid-treated synthetic silica-alumina to obtain Gaussian homo asym. polysiloxanes. The M_w was > 70 kg/mol, and the polymers were characterized using ²⁹Si NMR. The polymers were also characterized by measuring the refractive index, second virial coefficient (A₂), radius of gyration, weight-average mol. weight, number-average mol. weight and polydispersity using a gel permeation chromatog./light scattering (GPC/LS) coupled system. The A₂ exptl. value for the two polymers (between 4 and 6.5 × 10^-4 mol/mL g²) indicated that toluene was a good solvent.

Sanchez, Raquel published the artcileEffect of the silicon chemical form on the emission intensity in inductively coupled plasma atomic emission spectrometry for xylene matrices, COA of Formula: C7H16Cl2Si, the publication is Journal of Analytical Atomic Spectrometry (2009), 24(4), 391-401, database is CAplus.

Silicon is present in petrol products under very different chem. forms. The effect of the silicon chem. form on the sensitivity was studied by inductively coupled plasma at. emission spectrometry (ICP-AES). Solutions containing sixteen different silicon organic compounds with the same silicon concentration were prepared in xylene. The studied compounds were: six siloxanes, nine silanes and a silicate. Their b.ps. ranged from 101° (hexamethyldisiloxane) to 310° (2,3,4-(epoxycyclohexyl)ethyltrimetoxysilane). The ICP-AES signal depended strongly on the silicon compound Thus, for a commonly used sample introduction system consisting of a cross-flow pneumatic nebulizer coupled to a Ryton double pass spray chamber, the signal varied by a factor of up to 17, depending on the compound For most studied cases, some siloxanes yielded higher emission intensities than silanes. Under some circumstances, hexylmethyldichlorosilane and dimethyldodecylchlorosilane also produced higher signals than the other studied silanes. To elucidate the possible mechanisms for these changes, experiments were performed to verify whether the origin could be assigned either to the plasma or to the sample introduction system. Using the Mg II/Mg I ratio, no significant change in the plasma characteristics was actually observed As regards the sample introduction system, (i) the primary aerosol, (ii) the transport and memory effects using continuous and discrete introduction modes, an alternative spray chamber, and a total consumption system (the TISIS system), and (iii) the tertiary aerosol, via an impactor, were studied. Addnl. experiments were carried out with an ultrasonic nebulizer. The Si behavior was compared to other elements, such as Cu, Mg, Mn and Zn. The Si behavior was not related to the pneumatic nebulizer and suggested that a fraction of silicon was transported towards the plasma as a vapor when it was present as hexamethyldisiloxane (i.e., the compound with the lowest b.p. among the species studied). In any case, the variability of the signal induced by the different silicon chem. forms was less significant for the TISIS than for cyclonic and ultrasonic nebulizer. The observed results were specific to silicon as the signal of the other elements did not significantly change with silicon chem. form. As a consequence, internal standardization was not appropriate for mitigating interferences on silicon when petroleum products were analyzed.

Sanchez, Raquel published the artcileMinimization of the effect of silicon chemical form in xylene matrices on ICP-AES performance, Formula: C7H16Cl2Si, the publication is Journal of Analytical Atomic Spectrometry (2009), 24(10), 1382-1388, database is CAplus.

It was shown previously that the influence of the silicon chem. form could be minimized in ICP-AES by using high efficiency sample introduction systems. The effects of two of the most different silicon chem. forms were minimized in ICP-AES by using near total sample consumption systems. The two tested devices were a single pass spray chamber equipped with wall heating (heated torch integrated sample introduction system, h-TISIS) and a demountable direct injection high efficiency nebulizer (d-DIHEN). A room temperature TISIS and a cyclonic spray chamber were taken as the reference systems. Solutions containing silicon as six different compounds in xylene were prepared and analyzed through ICP-AES. At low liquid flow rates, the h-TISIS improves the sensitivity and the limits of detection as compared to the d-DIHEN. In contrast, shorter wash-out times were obtained for the d-DIHEN. As regards to the effect of the silicon chem. form, h-TISIS and d-DIHEN have minimized it with respect to a conventional cyclonic spray chamber.

Roy, Aroop K. published the artcileThe First Alkene-Platinum-Silyl Complexes: Lifting the Hydrosilation Mechanism Shroud with Long-Lived Precatalytic Intermediates and True Pt Catalysts, Safety of Dichloro(hexyl)(methyl)silane, the publication is Journal of the American Chemical Society (2002), 124(32), 9510-9524, database is CAplus and MEDLINE.

The synthesis, characterization, and exploratory chem. of two classes of alkene-platinum-silyl complexes, which have been postulated as hydrosilation intermediates, are described in this report. The unique dimeric complexes 1, [R₃Si(μ-Cl)(η²-COD)Pt]₂ {R₃Si = Et₃Si, MeCl₂Si, Me₂ClSi, “(EtO)₃Si”, PhMe₂Si, and (Me₃SiO)Me₂Si; COD = cycloocta-1,5-diene}, and the bis-silyl complexes 2, (η⁴-COD)Pt(SiR₃)₂ (R₃Si = Cl₃Si, MeCl₂Si, Me₂ClSi, PhMe₂Si), are formed from the sequential reaction of 2 and 4 equivalent of the corresponding hydrosilanes, resp., with Pt(COD)Cl₂ in the presence of a small excess of COD. Complexes 1 are stable for many days in solution at room temperature but decompose via slow elimination of chlorosilane. Some of the bis-silyl compounds 2 are stable for extended periods under inert atm. and especially below 0°, either in the solid state or in solution (in the presence of a small excess of free COD). Complexes 2 display catalytic activity as discrete, mol., and mononuclear species for hydrosilation and isomerization reactions. Compound 2c (R₃Si = MeCl₂Si) was fully characterized via multinuclear NMR spectroscopy and x-ray crystal structure anal. The facile H-transfer rather than Si-transfer to bound COD provides exptl. support for the sequence of insertive steps in the Chalk-Harrod catalytic cycle, at least for Pt-catalyzed hydrosilation.

Murase, Hiroaki published the artcileSynthesis of polysilanes using Mg and Lewis acid and the consideration of this reaction mechanism, Application of Dichloro(hexyl)(methyl)silane, the publication is Materials Sciences and Applications (2015), 6(6), 576-590, database is CAplus.

Reduction of dichlorosilanes with Mg metal in the presence of LiCl and Lewis acid such as FeCl₂ or ZnCl₂ was found to be the highly practical method for the synthesis of polysilanes (PS). This method is so useful and practical that PS can be prepared by stirring dichlorosilanes at room temperature This method was successfully applied for the synthesis of various types of PS having a linear structure, a cyclic structure and silane-styrene copolymers as another type of PS. The structure of the reaction intermediates was also analyzed. At the initiation stage the results of FD-MS (Field desorption mass spectrometry) and GPC (Gel permeation chromatog.) showed that linear oligomers were mainly formed by stepwise reactions, and then the high polymers and cyclic oligomers were formed in parallel.

Synthesis of the monomers was improved by using the “sequential drop”. By this way, the yield of the monomers was increased, and drain of the materials was decreased as compared with “fully mixing”. Using Wurtz-type coupling of methylphenethyldichlorosilane and trichloromethylsilane branched polysilanes: P(MPES-to-MS) were synthesized by “pre-polymerization” and “mixing polymerization”.
