Usage

General Description

Thexyltrichlorosilane, also known as 1,3-Bis(trimethylsilyl)benzene, is a colorless to pale yellow liquid with a pungent odor. It is a chemical compound used primarily as a reagent in organic synthesis and as a building block for silane-based polymers and materials. Thexyltrichlorosilane is an important intermediate in the production of silicone polymers, which are widely used in industrial and consumer products such as adhesives, sealants, lubricants, and coatings. It reacts readily with a variety of nucleophiles and can undergo various chemical reactions such as hydrolysis and condensation to form a range of silicon-containing compounds. Due to its reactivity and potential hazards, Thexyltrichlorosilane should be handled and stored with care, following appropriate safety precautions to avoid exposure and accidents.

Photoreactions of silyliron(II) complexes Cp*Fe(CO)2SiMe3 (Cp* = η5-C5H5, η5-C5Me5) in the presence of trihydrosilanes

The photochemistry of silyliron(II) complexes Cp*Fe(CO)2SiMe3 (Cp* = η5-C5H5, η5-C5Me5) in the presence of trihydrosilanes is described.Three types of products were observed, depending on the bulkiness of the Cp* ligands and the substituents on the trihydrosilanes: (η5-C5H5)Fe(CO)2SiMe3 reacts with tert-alkylsilanes RSiH3 (R = tBu, C(Me2)2H) upon irradiation to give silylene-bridged diiron complexes (η5-C5H5)2Fe2(CO)3(μ-SiHR) in good yields.In contrast, (η5-C5Me5)Fe(CO)2SiMe3 reacts with the tert-alkylsilanes photochemically to give silyl monoiron complexes (η5-C5Me5)Fe(CO)2SiH2R exclusively.Using p-TolSiH3 instead of tert-alkylsilane, the main photolysis product was the hydridobis(silyl)iron complex Cp*Fe(CO)SiMe3(H)SiH2-p-Tol.The X-ray crystal structure analysis of (η5-C5H5)2Fe2(CO)3(μ-SiHtBu) revealed that this complex adopts a geometry in which the two Cp rings and a Si-H bond are located on the same side with respect to the SiFe2C four-membered ring 29Si NMR spectra of the silylene-bridged diiron complexes showed signals at remarkably low field (δ 235.5-289.1 ppm).A mechanism for the formation of these silylene-bridged diiron complexes is proposed.

Tertiary alkylsilane

A novel tertiary alkylsilane is disclosed, which is useful as a variety of starting materials such as for photoreactive materials including semiconductor materials, insulative materials and photoresists, polymerization initiators and silicone-based ceramics precursors and is contributive to the safe and efficient production of high grade semiconductors.
