Diclorometilfenilsilano

Descrição:

Diclorometilfenilsilano, com o número CAS 149-74-6, é um composto organossilícico caracterizado pela presença de um átomo de silício ligado a um grupo fenila, um grupo metila e dois átomos de cloro. Este composto geralmente aparece como um líquido incolor a amarelo pálido e é conhecido por sua reatividade, particularmente em reações de substituição nucleofílica devido à presença dos grupos funcionais clorados. É frequentemente utilizado como um agente de acoplamento de silano, melhorando a adesão entre materiais inorgânicos e polímeros orgânicos. Além disso, Diclorometilfenilsilano pode servir como um intermediário na síntese de vários compostos que contêm silício. Suas propriedades químicas incluem um ponto de ebulição relativamente baixo e solubilidade moderada em solventes orgânicos, tornando-o adequado para várias aplicações em ciência dos materiais e síntese orgânica. No entanto, deve ser manuseado com cuidado devido à sua potencial toxicidade e reatividade, particularmente na presença de umidade, o que pode levar à hidrólise e à liberação de ácido clorídrico. Medidas e protocolos de segurança adequados são essenciais ao trabalhar com este composto.

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.
