monosilane

Relatively low volativity of the substrates allows us to efficiently remove hydrogen gas without removing any monosilane during reaction.

Disiloxane reacts at low temperatures with aluminium halides to give the corresponding silyl and silylene halides and monosilane.

Iodosilane is the first product of the reaction between monosilane and iodine, the other products being di-, tri- and finally tetraiodosilane (silicon tetraiodide).

Trisilane is also yielded by thermal decomposition of monosilane and disilane at higher temperatures as demonstrated by Bowrey, Purnell and Walsh in the sixties.

Dichlorosilane was originally prepared in 1919 by the gas-phase reaction of monosilane, SiH, with hydrogen chloride, HCl, and then reported by Stock and Somieski.

Yet another small-scale route for the production of silane is from the action of sodium amalgam on dichlorosilane, SiHCl, to yield monosilane along with some yellow polymerized silicon hydride (SiH).

Thus the polymeric silicon hydrides are formed along with smaller silicon hydride oligomers and hydrogen gas from the spontaneous but slow decomposition, as well as from the accelerated thermolysis, of acyclic and cyclic liquid silanes that are higher in molecular weight than monosilane (SiH) and disilane (SiH).
