Chloro(methyl)diphenylsilane

Description:

Chloro(methyl)diphenylsilane, with the CAS number 144-79-6, is an organosilicon compound characterized by its silane structure, which includes a silicon atom bonded to two phenyl groups, a methyl group, and a chlorine atom. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the presence of the chlorine atom, which can participate in various chemical reactions, including nucleophilic substitution. Chloro(methyl)diphenylsilane is often used as a coupling agent in the synthesis of silicone polymers and as a precursor in the preparation of silane-modified materials. Its properties include moderate volatility and solubility in organic solvents, making it useful in various industrial applications. Safety precautions are necessary when handling this compound, as it can be irritating to the skin and eyes, and its vapors may be harmful if inhaled. Proper storage in a cool, dry place away from moisture is also essential to maintain its stability.

Phenyl-Containing Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
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.
