Usage

General Description

N-PROPYLDIMETHYLCHLOROSILANE is a chemical compound with the formula C5H13ClSi. It is a colorless to pale yellow liquid with a pungent odor. N-PROPYLDIMETHYLCHLOROSILANE is commonly used as a surface modifier in the production of various polymeric materials, including plastics, rubbers, and adhesives. It is also used as a crosslinking agent in the formulation of silicone polymers and resins. N-PROPYLDIMETHYLCHLOROSILANE is a highly reactive organosilane compound that undergoes hydrolysis in the presence of water to form silanol groups, which can then react with other functional groups on surfaces to provide adhesion and chemical bonding. It is important to handle this chemical with care, as it can cause skin and eye irritation and is harmful if inhaled or ingested. Proper safety precautions should be taken when working with N-PROPYLDIMETHYLCHLOROSILANE, including the use of personal protective equipment and adequate ventilation.

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.

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.
