• Description: Silicon forms a series of hydrides known as silanes, formula SinH2n+2, where n is the number of silicon atoms in the molecule. This general formula for the silicon hydrides is similar to the CnH2n+2 for the alkane class of hydrocarbons.

Technology Process of Disilylsilane

There total 30 articles about Disilylsilane which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 55.0%

potassium (7440-09-7) + monosilane (7440-21-3) + Nonafluorobutansulfonsaeure-silylester (135524-36-6) → trisilane (7783-26-8,134303-33-6) + disilane (1590-87-0) + isotetrasilane (13597-87-0) + neopentasilane (15947-57-6)

Guidance literature:

In diethylene glycol dimethyl ether; byproducts: H2; further intermediate: KSiH3; under N2, dispersion of potassium reacts with SiH4 at 100°C, concd. in vacuo at 30°C, C4F9SO3SiH3 added at -60°C, stored at this temp. for 10 min, warmed to 40°C; volatiles removed over 3 h in vacuo, SiH4 removed; GC;

Reference yield: 55.0%

sodium (7440-23-5) + monosilane (7440-21-3) + Nonafluorobutansulfonsaeure-silylester (135524-36-6) → trisilane (7783-26-8,134303-33-6) + disilane (1590-87-0) + isotetrasilane (13597-87-0) + neopentasilane (15947-57-6)

Guidance literature:
