General Description

MethoxyMethyltrichlorosilane is a chemical compound with the formula CH3SiCl3O. It is a colorless liquid that is used as a coupling agent in the production of various materials, such as adhesives, sealants, and coatings. MethoxyMethyltrichlorosilane is commonly employed in the manufacture of silicone resins and as a crosslinking agent for polymers. It is also used as a water-repellent and surface treatment for glass, metal, and plastic surfaces. The chemical is corrosive and must be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. Additionally, it is flammable and should be stored and handled away from sources of ignition.

Synthesis and structures of simple (silylmethyl)(methyl)ethers

The compound Cl3SiCH2OCH3 was prepared by reacting ClCH2OCH3 with the Cl3SiH/NEt 3 reagent. H3SiCH2OCH3 and F 3SiCH2OCH3 were synthesized from Cl 3SiCH2OCH3 by reduction with LiAlH4 and by fluorination with SbF3, respectively. The crystal structures of the low-melting compounds H3SiCH2OCH3 and F3SiCH2OCH3 were determined by X-ray diffraction of in situ grown crystals. Both compounds do not show any observable β-donor-acceptor interactions, but behave structurally like usual dialkylethers or silanes, as is obvious from the structural parameters in H3SiCH2OCH3 (3SiCH2OCH 3 (SiCO 107.1(1), COC 111.2(2)°). Earlier postulates of Si?O interactions in compounds with SiCO units could thus not be confirmed on a structural basis.

METHOD FOR PRODUCING ALKOXY HYDROSILANE

Provided is a method for producing an alkoxyhydrosilane, comprising: a reaction (reaction 1) of a halohydrosilane compound (B) represented by H-SiR2c(CR13-bYb)aX3-a-c wherein R1 is a hydrogen atom or C1-20 hydrocarbon group; R2 is a C1-20 hydrocarbon group; X is a halogen atom; Y is a hetero substituent; a is 1 or 2, b is 1, 2 or 3, and c is 1 or 0, provided that a+c is not more than 2, with an alcohol (C) in an amount of 0.50-0.99 molar equivalents relative to Xs of the halohydrosilane compound (B); followed by a reaction (reaction 2) with an orthoester (D) in an amount of 1.00 molar equivalent or more relative to the residual Si-X in the reaction mixture, to produce an alkoxyhydrosilane compound (A) represented by H-SiR2c(CR13-bYb)a(OR8)3-a-c wherein R8 is a C1-20 hydrocarbon group, and R1, R2, Y, a, b, and c are as defined above.
