Technology Process of Tribromosilane

There total 13 articles about Tribromosilane 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:

dibromochlorosilane (82146-27-8) + trimethylstannane (1631-73-8) → tribromosilane (7789-57-3) + SiClBrH2 (21479-75-4) + SiCl2HBr (82146-25-6) + trichlorosilane (10025-78-2) + monosilane (7440-21-3)

Guidance literature:

In neat (no solvent); condensing of equimolar amts. of tinhydride and SiClHBr2 (trace of SiCl2HBr present) into cold finger, reaction at room temp. (30 min); further products; not isolated; IR spectroscopy;

Reference yield:

bromine (7726-95-6) + monosilane (7440-21-3) → tribromosilane (7789-57-3) + silyl bromide (14791-57-2) + dibromosilane (13768-94-0) + hydrogen bromide (10035-10-6,12258-64-9) + tetrabromosilane (7789-66-4)

Guidance literature:

In neat (no solvent); reaction of Br2 and excess SiH4; cooling;; fractionation;;

Reference yield:

Cu(b),Si(20) (W%) + hydrogen bromide (10035-10-6,12258-64-9) → tribromosilane (7789-57-3) + copper(I) bromide (7787-70-4)
