CAS 694-53-1

Phenylsilane

Description:

Phenylsilane, with the CAS number 694-53-1, is an organosilicon compound characterized by the presence of a phenyl group attached to a silicon atom. It typically appears as a colorless to pale yellow liquid with a distinctive odor. This compound is known for its low viscosity and volatility, making it useful in various chemical applications. Phenylsilane exhibits reactivity due to the presence of Si-H bonds, allowing it to participate in hydrosilylation reactions and serve as a precursor for silicone polymers. Its chemical structure contributes to its ability to enhance the thermal and mechanical properties of materials when used as an additive. Additionally, phenylsilane can be utilized in the synthesis of other organosilicon compounds and in surface modification processes. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it can be flammable and irritating to the skin and eyes. Overall, phenylsilane is a versatile compound with significant applications in materials science and organic synthesis.

Mono-substituted Silane Reducing Agent
Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
Trihydridosilane
Silyl Hydrides are a distinct class of silanes that behave and react very differently than conventional silane coupling agents. They react with the liberation of byproduct hydrogen. Silyl hydrides can react with hydroxylic surfaces under both non-catalyzed and catalyzed conditions by a dehydrogenative coupling mechanism. Trihydridosilanes react with a variety of pure metal surfaces including gold, titanium, zirconium and amorphous silicon, by a dissociative adsorption mechanism. The reactions generally take place at room temperature and can be conducted in the vapor phase or with the pure silane or solutions of the silane in aprotic solvents. Deposition should not be conducted in water, alcohol or protic solvents.

Phenylsilane

CAS: 694-53-1

Phenylsilane is a model system for the study of the reaction mechanism of nucleophilic substitution. It is used to investigate the steric interactions between a substrate molecule and an electrophile that are important in determining the rate of reactivity. Phenylsilane has been shown to have antioxidative properties, which may be due to its ability to scavenge reactive oxygen species (ROS), such as hydroxyl radicals, superoxide ions, and hydrogen peroxide. Phenylsilane also has low kinetic energy and can form hydrogen bonds with carbonyl groups and amines. This chemical substance can react with quinoline derivatives, including benzoquinone, which is a toxic by-product of the metabolism of many drugs.
