Silyl hydride
Sign in to saveHydrosilanes 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 terminated with hydrosilanes are resins that are used to make useful materials like caulks.

==Synthesis== Trichlorosilane is produced commercially by the reaction of hydrogen chloride with silicon: Si + 3 HCl → HSiCl3 + H2 Many alkoxy hydrosilanes are generated by alcoholysis of trichlorosilane. One example is triethoxysilane: HSiCl3 + 3EtOH → HSi(OEt)3 + 3 HCl
