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.

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.

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.
