A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes

Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si-Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5, and tetrachlorosilane 6 to give the corresponding monochlorosilanes.

Mechanistic insights into the iridium-catalyzed hydrosilylation of allyl compounds

The hydrosilylation of allyl compounds is very important for the industrial production of γ-substituted propylsilanes; however, it is also a process known to suffer from either substantial selectivity issues or short catalyst lifetimes. While there are reports on the platinum-catalyzed variant, this study is the first comprehensive work on the more recently employed iridium-catalyzed process. A combination of stoichiometric and catalytic experiments as well as reactions with isotope-labeled compounds is used to elucidate the critical parameters influencing the catalytic performance and to identify the main deactivation pathways. This report is intended to pave the way toward the optimization of current iridium-catalyzed processes and the design and synthesis of improved catalyst structures.

PRODUCTION OF ORGANOSILANES IN THE PRESENCE OF IRIDIUM-CATALYSTS AND COCATALYSTS

The invention relates to a method for producing silanes of general formula (I) R6R5CH-R4CH-SiR1R2R3 (I), wherein silanes of general formula (II) HsiR1R2R3 (II) are reacted with alcenes and/or allcynes of general formula (III) R6R5C=CHR4 (III), in the presence of iridium compounds as catalysts and in the presence of cocatalysts according to claim 1. The amount of cocatalysts is between 0.5 wt.- % to 5.0 wt.- %, in relation to the total weight of the used components of general formulae (II) and (III). According to the invention, R1, R2, R3, R4, R5, R6 and R have the meaning cited in claim 1.

Hydrosilylation of cyclohexene and allyl chloride with trichloro-, dichloro(methyl)-, and chlorodimethylsilanes in the presence of Pt(0) complexes

Hydrosilylation of cyclohexene and allyl chloride in the presence of Pt(0) complexes with tetramethyldivinyldisiloxane (Karstedt catalyst) and hexavinyldisiloxane was studied. It was shown that these catalysts are much more active in the hydrosilylation of cyclohexene with trichloro-, dichloro(methyl)-, and chlorodimethylsilane than the Pt(II)-containing Speier catalyst. In the hydrosilylation of allyl chloride in the presence of Pt(0) complexes, the ratio of the fraction of addition products to the fraction of reduction products increases from 5.7 (Speier catalyst) to 10-16. Quantum-chemical calculations showed that Pt(0) complexes are more active than Pt(II) complexes on the stage of formation of platinum silicon hydride complexes. Pleiades Publishing, Inc., 2006.

Method for obtaining halogenated monoorganoxysilanes useful in particular as synthesis intermediates

The invention concerns the preparation of halogenated monoorganoxysilanes, of formula (I), said compounds being useful as synthesis intermediate in organic chemistry. Said method for preparing monoorganoxysilanes consists in: using as starting product halogenoalkylsilanes of the (CH3)2SiCl2 type and in substituting the silicon with a radical bearing a divalent unit bound to an electrophilic reactive group capable of reacting with at least an appropriate nucleophilic agent to form a functionalised monoorganoxysilane of formula (II) with, for example: R=C1-C4 alkyl; R, R=C1-C6 alkyl; B═C1-C10 alkylene; m=1 or 2; Hal=halogen; W=amino, mercapto, (organosilyl)-organopolythio radical.

246. Monofunctional (Dimethylamino)silane as Silylating Agent

The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied.These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine.The resulting products are thermally stable and relatively volatile.Reaction with surface-hydrated silicon-dioxide preparations at a50-250 deg C for 170 h yields a dense grafted layer.However, with (dimethylamino)silanes having strongly polar substituents, a retreatment of the surface-modified silica seems to be necessary in order to attain maximum coverage.

SILAETHENE I. DARSTELLUNG UND CHARAKTERISIERUNG VON MONOSILACYCLOBUTANEN

Monosilacyclobutanes of the type RR' are prepared by ring closure reactions of 3-halopropylhalosilanes and by substitution of SiCl containing silacyclobutane rings with organometallic reagents (RMgX, LiR, NaCp).Under optimal experimental conditions yields between 50 and 95percent can be obtained by both procedures.Characterization of the compounds is accomplished by analytical (C, H, N) and NMR, IR and mass spectroscopic investigations.
