Dichloromethylphenylsilane

Description:

Dichloromethylphenylsilane, with the CAS number 149-74-6, is an organosilicon compound characterized by the presence of a silicon atom bonded to a phenyl group, a methyl group, and two chlorine atoms. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity, particularly in nucleophilic substitution reactions due to the presence of the chlorinated functional groups. It is often used as a silane coupling agent, enhancing the adhesion between inorganic materials and organic polymers. Additionally, dichloromethylphenylsilane can serve as an intermediate in the synthesis of various silicon-containing compounds. Its chemical properties include a relatively low boiling point and moderate solubility in organic solvents, making it suitable for various applications in materials science and organic synthesis. However, it should be handled with care due to its potential toxicity and reactivity, particularly in the presence of moisture, which can lead to hydrolysis and the release of hydrochloric acid. Proper safety measures and protocols are essential when working with this compound.

Aromatic Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
Arylsilane Cross-Coupling Agent
The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
