One-pot reduction-hydrophobization of heterogenized platinum with 1,1,3,3-tetramethyldisiloxane

An original approach for the design of hydrophobized heterogeneous platinum-based catalytic systems is reported here. Heterogenization was performed by depositing the platinum precursor (H2PtCl6) on macroporous styrene-divinylbenzene (SDVB) beads with a high surface area, -330 m2?g?1, as determined by N2 sorption data, followed by treating with 1,1,3,3-tetramethyldisiloxane (TMDS) as Pt(IV) reducing agent without the need of special conditions. Simultaneously, the coupling by Si-O-Si bonds of the TMDS oxidation or hydrolysis intermediates endowed the SDVB-Pt systems with an enhanced hydrophobicity (up to 10 times higher than that of SDVB support). In addition, to obtain an optimum catalytic system, which stabilize the supported platinium against leaching, several mixtures of TMDS with other methylsiloxane precursors, namely, methyltrimethoxysilane (MTMS), (Formula presented.)-bis(trimethylsiloxy)poly(dimethylsiloxane-H-methylsiloxane) (PDMHS), and (Formula presented.)-bis(trimethylsiloxy)poly(dimethylsiloxane-co-vinylmethylsiloxane) (PDMVS), have been systematically investigated. The reduction of platinum, visible by an instant change in the color from yellow to black, was confirmed by X-ray photoelectron spectroscopy analysis, while its total content in the samples was determined quantitatively by atomic absorption spectroscopy. The obtained systems have been preliminarily assessed for catalytic activity in the hydrosilylation of 1,3-bis(vinyl)tetramethyldisiloxane and allyl alcohol with TMDS, and 1-hexene with trimethoxysilane, as model reactions. The results indicate the high suitability of these systems as catalysts for the selective anti-Markovnikov hydrosilylation of alkenes, as well as for the very fast oxidation-condensation homocoupling of H-silanes in presence of a green oxidation agent (air), under mild conditions, with the release of hydrogen and its in situ addition to the double bond.

Silicone sealant cross-linking agent and its preparation method and application

The invention discloses a silicone sealant cross-linking agent, and a preparation method and an application of the silicone sealant cross-linking agent. The preparation method comprises the steps that long-chain alkyl trichlorosilane serves as a cross-linking agent precursor and reacts with a remover, and then the cross-linking agent is obtained. Long-chain alkyl trichlorosilane is C6-C18 alkyl trichlorosilane, and the cross-linking agent is applied to preparation of a silicone sealant. According to the cross-linking agent, long-chain alkyl is added and exerts a plasticizer effect, and in a silicone sealant preparation process, long-chain alkyl is bonded in a high molecular material by a chemical bond, so that the prepared sealant is free from leaked oil pollution.

Convenient synthesis of alkoxyhalosilanes from hydrosilanes

Selective dehydrogenative coupling of di- and trihydrosilanes with alcohols catalyzed by PdCl2 or NiCl2 afforded alkoxyhydro- and dialkoxyhydrosilanes in good yield. Further treatment of the resulting alkoxyhydrosilanes with carbon tetrachloride or allyl bromide in the presence of the same catalyst led to the formation of alkoxychloro- and alkoxybromosilanes, respectively. Similar reactions of dialkoxyhydrosilanes with carbon tetrachloride afforded dialkoxychlorosilanes in good yield, although contamination of small amounts of trialkoxysilanes and alkoxydichlorosilanes was detected in the products. Selective substitution of the alkoxyhalosilanes with nucleophiles is also reported.
