WebMar 22, 2024 · This review presents a comprehensive picture of the development of transition metal-catalyzed hydrosilanes-mediated intramolecular C (sp 2 )−H and C (sp 3 )−H silylation organized by their reaction types and mechanisms. Hydrosilanes are tetravalent silicon compounds containing one or more Si-H bond. The parent hydrosilane is silane (SiH4). Commonly, hydrosilane refers to organosilicon derivatives. Examples include phenylsilane (PhSiH3) and triethoxysilane ((C2H5O)3SiH). Polymers and oligomers … See more Trichlorosilane is produced commercially by the reaction of hydrogen chloride with silicon: Si + 3 HCl → HSiCl3 + H2 Many alkoxy hydrosilanes are generated by See more Setting aside silane itself, for which is used mainly in the microelectronics industry as a source of Si, hydrosilanes participate in many reactions. Hydrosilanes are mainly used for diverse styles of reduction in both industrial and laboratory-scale reactions. These including … See more The silicon-to-hydrogen bond is longer than the C–H bond (148 compared to 105 pm). The Si-H bond is about 10% weaker compared to C-H bonds. Hydrogen is more electronegative than silicon (hence the naming convention of silyl hydrides), … See more • Hydrogen-terminated silicon surface See more • Ramírez-Oliva, Eulalia; Hernández, Alejandro; Martínez-Rosales, J.
