Description

2-(Diphenylphosphino)ethyltriethoxysilane Description:

(Diphenylphosphino)ethyltriethoxysilane, also known by its chemical name diphenylphosphinoethyltriethoxysilane, is an organosilicon compound that incorporates both phosphine and silane functional groups. Its molecular structure consists of two phenyl groups attached to a phosphorus atom (PPh₂), connected via an ethyl linker to a silicon atom, which is further bonded to three ethoxy groups (—OCH₂CH₃). The chemical formula is typically represented as C₂H₅Si(OC₂H₅)₃P(C₆H₅)₂.
