Uses

Used in Coatings Industry:
Diisopropoxydimethylsilane is used as a coupling agent to enhance the adhesion and durability of coatings. Its strong chemical bonding capabilities improve the overall performance and longevity of the coatings, making them more resistant to wear and environmental factors.
Used in Adhesives Industry:
In the adhesives industry, diisopropoxydimethylsilane serves as a coupling agent, which strengthens the bond between the adhesive and the materials being joined. This results in improved adhesive performance and increased durability of the bonded products.
Used in Sealants Industry:
Diisopropoxydimethylsilane is used as a crosslinking agent in the production of silicone polymers for sealants. This contributes to the formation of a robust and flexible sealant that can withstand various environmental conditions and maintain its sealing properties over time.
Used in Waterproof Coatings and Sealants Development:
Leveraging its water-repellent and protective properties, diisopropoxydimethylsilane is used in the development of waterproof coatings and sealants. This application ensures that the treated surfaces remain protected from water damage and retain their integrity for an extended period.

Selective Formation of Alkoxychlorosilanes and Organotrialkoxysilane with Four Different Substituents by Intermolecular Exchange Reaction

Alkoxychlorosilanes are scientifically and industrially important toward preparing silicone and silica as well as preparation of siloxane-based nanomaterials by stepwise reactions of Si?OR (R=alkyl) and Si?Cl groups. Intermolecular exchange of alkoxy and chloro groups between alkoxysilanes and chlorosilanes (functional group exchange reaction) provides an efficient and environmentally benign route to alkoxychlorosilanes. BiCl3 as a Lewis acid catalyst can promote the functional group exchange reactions more efficiently than conventional acid catalysts. Higher reactivity has been observed for chlorosilanes with smaller numbers of Si?CH3 groups and for alkoxysilanes with larger numbers of Si?CH3 groups. The reaction mechanism is proposed and selective syntheses of alkoxychlorosilanes are demonstrated. These findings also enable us to synthesize an organotrialkoxysilane with four different substituents.

Synthesis of Preceramic Organometallic Polymers by Reaction of Titanium and Zirconium Alkoxides with Silazanes

The main features of model reactions of titanium and zirconium alkoxides with silazanes were studied. A method was developed for incorporating titanium and zirconium atoms into the structure of silazane polymers prepared by coammonolysis of dichlorodimethylsilane and trichloromethylsilane or by catalytic polycondensation of dimethylcyclosilazanes. These polymers were studied as ceramics precursors.

N-(DIMETHYLALKOXYSILYLMETHYL)- AND N-(DIMETHYLARYLOXYSILYLMETHYL)LACTAMS

A comparison is made of conditions and preparative possibilities of synthesizing Si-substituted N-(dimethylsilylmethyl)lactams with oxygen-containing substituents (alkoxides, aryloxides, benzoates, and triflates) by several methods: by reactions of N-(dimethylchlorosilylmethyl)lactams with sodium alkoxides and with alcohols in the presence of triethylamine, by exchange reactions with trimethylsilyl derivatives of alcohols, phenols, benzoic and trifluoromethylsulfonic acids, and also by a one-pot technique using lactam, dimethylchloromethylchlorosilane, and triethylamine with subsequent addition to the reaction mixture of the alcohol and triethylamine. In the reaction of N-(dimethylchlorosilylmethyl)lactams with sodium alkoxides, concurrently with the replacement of halogen by an alkoxy group the Si-C bond is split to form N-methyllactams, which can also be prepared by the reaction of the initial chlorides with potassium hydroxide. According to IR spectroscopy, intramolecular O->Si coordination is observed in aryloxy-, benzoyloxy-, and trifluoromethylsulfonyloxy derivatives of N-(dimethylsilylmethyl)lactams, whereas the corresponding alkoxy derivatives lack this interaction. The structure of 1-(dimethylsilylmethyl)-2-pyrrolidone phenoxide and benzoate, 1-(dimethylpentafluorophenoxysilylmethyl)perhydro-2-azepinone, and 1-(dimethyltrifluoromethylsulfonyloxymethyl)-2-piperidone was studied by x-ray structural analysis. The lengths of the axial (C=)O->Si and Si-O bonds are, respectively, 2.367 and 1.711(2) Angstroem for the first, 2.228 and 1.711(2) Angstroem for the second, 2.078 and 1.787(2) Angstroem for the third, and 1.753 and 2.785(2) Angstroem for the fourth compound. Variations in the bond lengths are due to the properties of the Si-substituent and to the size of the lactam rings. The ease of formation of the Si-substituted N-(dimethylsilylmethyl)lactams with oxygen-containing substituents via the exchange reaction of N-(dimethylchloromethyl)lactams with the corresponding trimethylsiloxy derivatives correlates with the strength of the silicon-oxygen coordination in the reaction products.
