Trisilane synthesis

WebEight methyl derivatives of disilane, trisilane and tetrasilane, containing the silicon-hydrogen bond, have been prepared from the reaction of appropriate halogen- or ethoxyl-substituted polysilanes with lithium aluminum hydride. Preparation of several new organopolysilanes as intermediates for synthesis of these hydrides is also described. Trisilane was characterized by Alfred Stock having prepared it by the reaction of hydrochloric acid and magnesium silicide. This reaction had been explored as early as 1857 by Friedrich Woehler and Heinrich Buff, and further investigated by Henri Moissan and Samuel Smiles in 1902. See more Trisilane is the silane with the formula H2Si(SiH3)2. A liquid at standard temperature and pressure, it is a silicon analogue of propane. In contrast with propane, however, trisilane ignites spontaneously in air. See more The key property of trisilane is its thermal lability. It degrades to silicon films and SiH4 according to this idealized equation: Si3H8 → Si + 2 SiH4 See more
