Organic boron & silicon products - Alfa Aesar

The organoboron, and organosilicon compounds are compounds with carbon-boron, and carbon-silicon bonds respectively. The C-B bond has low polarity and due to its lower electronegativity, boron often forms electron-deficient compounds. Due to the large difference in electronegativity, organosilicon compounds do not involve double bonds like its carbon counterparts. The class of boron compounds have formula BRnH3-n. Examples of boronic compounds include: boronic acids, anhydrides and its esters (BRn(OR)3-n), borate esters, boranes, organoborate salts, organic tetrafluoroborates, trifluoroborates, boron-substituted aromatic compounds (eg.C5H5B-pyridine), and boryl compounds (R2B). The boron based reagents are used to reduce ketones enantioselctively in a stoichometric and catalytic approach. Due to the presence of (sp3)C-B, (sp2)C-B and (sp)C-B bonds, organoboran compounds provide corresponding coupled products with various organic electrophiles in coupling reactions, which are stereo- and regioselective. The Suzuki coupling reaction (involving boron compounds), plays an important role in combinatorial and parallel methodologies in studying chemical reactivity, particularly in medicinal chemistry. Organo silicon compounds are colorless, thermally stable and highly soluble in hydrocarbons, chlorinated hydrocarbons, ethers, and other organic solvents. Organosilicon compounds are readily hydrolyzed. Silanols, silanes, siloxanes, silyl halides are examples of silicon products. Organosilicon compounds show a vast array of applications in chemical research and industry. Silicone products are widely used in various manufacturing sectors for the preparation of defoamers, healthcare products, adhesives, computers, dry cleaning solvents, lubricants (automotive field), cooking utensils, thermal insulation, construction and architecture materials, and electrical insulations; many fabrics are coated with silicone to form a strong, waterproof composite.
