78-62-6 Usage
Description
Diethoxydimethylsilane is an intermediate silane compound known for its ability to modify various materials and surfaces, as well as its utility in organic synthesis reactions. It is characterized by its capacity to block hydroxyl and amino groups, enabling subsequent reactions that would otherwise be hindered by the presence of active hydrogen in these groups. Diethoxydimethylsilane can be hydrolyzed to recover the original hydroxyl or amine groups, making it a versatile agent in chemical processes.
Uses
Used in Surface Modification:
Diethoxydimethylsilane is used as a surface modifier for materials such as epoxy resins, pure silica, and Pd/SiO2 hydrogen gas sensors. The surface modification enhances the gas sensing properties of these sensors, improving their performance and reliability.
Used in Synthesis of Advanced Materials:
Diethoxydimethylsilane serves as a precursor for the synthesis of ultrafine SiC (silicon carbide) powder, a material with high strength, hardness, and thermal stability, making it suitable for various high-performance applications.
Used in Organic Synthesis:
Diethoxydimethylsilane is used as a silylating agent in organic synthesis reactions, where it blocks hydroxyl and amino groups. This step is crucial for carrying out reactions that would be adversely affected by the presence of active hydrogen in these groups. The blocked groups can be recovered through a hydrolysis procedure, allowing for the continuation of the synthesis process.
Used in the Preparation of Specialized Materials:
Diethoxydimethylsilane is utilized in the preparation of hydrophobic and release materials, which have applications in various industries, including coatings, adhesives, and composites. Additionally, it enhances the flow of powders, which is beneficial in manufacturing processes that require the handling of powdery substances.
Used in Advanced Material Research:
Studies have reported the use of diethoxydimethylsilane as a precursor for ORMOSIL (Organically modified SILicates) and the development of thin a-SiOxCyHz films. These advanced materials have potential applications in various fields, such as electronics, optics, and materials science.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction.. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions. These materials may be nontoxic.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Flammability and Explosibility
Flammable
Safety Profile
Mildly toxic by
inhalation and ingestion. A skin and eye
irritant. A dangerous fire hazard when
exposed to heat, flame, or oxidizers. When
heated to decomposition it emits acrid
smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 78-62-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78-62:
(4*7)+(3*8)+(2*6)+(1*2)=66
66 % 10 = 6
So 78-62-6 is a valid CAS Registry Number.

Hydrogenolysis of Polysilanes Catalyzed by Low-Valent Nickel Complexes

The dehydrogenation of organosilanes (RxSiH4?x) under the formation of Si?Si bonds is an intensively investigated process leading to oligo- or polysilanes. The reverse reaction is little studied. To date, the hydrogenolysis of Si?Si bonds requires very harsh conditions and is very unselective, leading to multiple side products. Herein, we describe a new catalytic hydrogenation of oligo- and polysilanes that is highly selective and proceeds under mild conditions. New low-valent nickel hydride complexes are used as catalysts and secondary silanes, RR′SiH2, are obtained as products in high purity.
Nucleophile induced ligand rearrangement reactions of alkoxy- and arylsilanes

The ligand-redistribution reactions of aryl- and alkoxy-hydrosilanes can potentially cause the formation of gaseous hydrosilanes, which are flammable and pyrophoric. The ability of generic nucleophiles to initiate the ligand-redistribution reaction of commonly used hydrosilane reagents was investigated, alongside methods to hinder and halt the formation of hazardous hydrosilanes. Our results show that the ligand-redistribution reaction can be completely inhibited by common electrophiles and first-row transition metal pre-catalysts.
