Technology Process of Silylsilane

There total 71 articles about Silylsilane 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: 87.0%

lithium aluminium tetrahydride (16853-85-3) + tetrachlorosilane (10026-04-7,53609-55-5) + hexachlorodisilane (13465-77-5) → disilane (1590-87-0) + monosilane (7440-21-3)

Guidance literature:

In diethyl ether; reaction of a ether soln. of Si2Cl6 with a ether solution of LiAlH4 (in 15% exceed) in a vacuum at 0 °C;;

Reference yield: 45.0%

lithium aluminium tetrahydride (16853-85-3) + SiF3SiHBr2 (56144-86-6) → disilane (1590-87-0) + trifluorosilane (13465-71-9) + silicon tetrafluoride (7783-61-1)

Guidance literature:

React. occurs at room temp. (N2 or Ar, 15 min).; IR spectrum of volatile material indicates resulting compounds and 5% unreacted SiF3SiHBr2.;

Reference yield: 2.0%

monosilane (7440-21-3) → trisilane (7783-26-8,134303-33-6) + disilane (1590-87-0) + silicon (7440-21-3)

Guidance literature:

In gaseous matrix; byproducts: H2; other Radiation; photolysis of pure SiH4 or a 37% mixture with N2 or Ar or H2 or He (total pressure = 80 Torr) in stainless steel cell by cw CO2 laser (945.98 cm**-1=IR), strong luminescence accompanies the react.; traces of higher silanes (gases) and solid hydrogenated silicon also present, H2 or He inhibit the react.;
