Technology Process of Tribromo(fluoro)silane

There total 1 articles about Tribromo(fluoro)silane 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:

difluorosilylene (13966-66-0) + bromine (7726-95-6) + silicon tetrafluoride (7783-61-1) → bromotrifluorosilane (14049-39-9) + difluoro dibromosilane (14188-35-3) + fluoro tribromosilane (18356-67-7) + disilicon hexabromide (13517-13-0) + tetrabromosilane (7789-66-4)

Guidance literature:

In neat (no solvent); The halogen was co-condensed in a flask at -196°C with the mixt. of SiF4 and SiF2 emerging out of the reactor tube; further products;; warmed to room temp.; the volatile products were sepd. and detected by NMR and MS;;

Reference yield:

fluoro tribromosilane (18356-67-7) + trimethylstannane (1631-73-8) → difluorosilane (13824-36-7) + trifluorosilane (13465-71-9) + monosilane (7440-21-3)

Guidance literature:

In neat (no solvent); inert atmosphere (N2, Ar or high vac.), room temperature, three equiv. of tinhydride, reactn. time 0.5 h; not isolated; IR spectroscopy (identified 60% SiH4, 20% SiF3H and 20% SiF2H2 in product mixt.);

Reference yield:

fluoro tribromosilane (18356-67-7) + antimony(III) chloride (10025-91-9) → bromodichlorofluorosilane (28054-58-2) + dibromochlorofluorosilane (28054-61-7) + trichloro fluorosilane (14965-52-7)
