Diclorometilfenilsilano

Descrizione:

Diclorometilfenilsilano, con il numero CAS 149-74-6, è un composto organosiliconico caratterizzato dalla presenza di un atomo di silicio legato a un gruppo fenile, un gruppo metile e due atomi di cloro. Questo composto appare tipicamente come un liquido incolore o giallo pallido ed è noto per la sua reattività, in particolare nelle reazioni di sostituzione nucleofila a causa della presenza dei gruppi funzionali clorurati. Viene spesso utilizzato come agente accoppiatore di silano, migliorando l'adesione tra materiali inorganici e polimeri organici. Inoltre, Diclorometilfenilsilano può fungere da intermedio nella sintesi di vari composti contenenti silicio. Le sue proprietà chimiche includono un punto di ebollizione relativamente basso e una solubilità moderata nei solventi organici, rendendolo adatto per varie applicazioni nella scienza dei materiali e nella sintesi organica. Tuttavia, deve essere maneggiato con cura a causa della sua potenziale tossicità e reattività, in particolare in presenza di umidità, che può portare a idrolisi e alla liberazione di acido cloridrico. Misure e protocolli di sicurezza adeguati sono essenziali quando si lavora con questo 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.
