Usage

General Description

Disiloxane, hexabutyl- is a chemical compound that belongs to the class of organosilicon compounds. It is a clear, colorless liquid with a fruity odor and is used for its solvent properties in various industrial applications. Hexabutyl disiloxane is also used as a defoaming agent, as well as an additive in the production of silicone polymers and resins. It is considered to have low toxicity and is generally regarded as safe for use in industrial and commercial settings. However, appropriate handling and safety precautions should still be observed when working with this chemical.

Copper-Containing Polyoxometalate-Based Metal-Organic Framework as a Catalyst for the Oxidation of Silanes: Effective Cooperative Catalysis by Metal Sites and POM Precursor

The oxidation of silanes into silanols is a very necessary transformation, and yet the rational fabrication of efficient catalysts for this reaction remains a challenging task. Here, a 3D polyoxometalate-based metal-organic framework (POMOF), [Cu3(pz)3{PMo12O40}]·H2O (HENU-8, HENU = Henan University; pz = pyrazine) was consciously prepared and first employed in the oxidation of dimethylphenylsilane with tert-butyl hydroperoxide (TBHP) as an oxidant, achieving 89% yield at a production rate of 132 mmol·g-1·h-1. Control experiments indicated that polyoxometalates and Cu atoms together affected the ultimate outcome in this catalytic system, and the designed catalyst followed a free radical mechanism.

New access to organoacyloxytrialkylsilanes

In this article, we present the synthesis of acetoxytributylsilane, obtained from methoxytributylsilane and acetic anhydride, under different conditions (catalyst, temperature, reaction time). Access to other acyloxytributylsilanes from different anhydrides is also presented. Copyright Taylor & Francis Group, LLC.
