Technology Process of bromo(difluoro)silane

There total 2 articles about bromo(difluoro)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:

difluoro dibromosilane (14188-35-3) + trimethylstannane (1631-73-8) → SiF2HBr (82146-23-4) + trimethyltin bromide (1066-44-0)

Guidance literature:

In neat (no solvent); equimolar amts. of Me3SnH and SiF2Br2 room temp., 12 h; removing Me3SnBr by trap (pentane) cooling to -131°C, cooling to -196°C; not isolated; Ir, (1)H- and (19)F-NMR spectroscopy (identified 90% SiF2HBr in product mixt.);

Reference yield:

difluoro dibromosilane (14188-35-3) + triethylstannane (997-50-2) → SiF2HBr (82146-23-4) + triethyltin bromide (2767-54-6)

Guidance literature:

In neat (no solvent); equimolar amts. of Et3SnH and SiF2Br2, warming to room temperature (12 h); removing Et3SnBr by trap (pentane) cooling to -131°C, cooling -196°C; not isolated; IR, (1)H-NMR, (19)F-NMR (identified 90% SiF2HBr in product mixt.);

Reference yield:

SiF2HBr (82146-23-4) + triethylstannane (997-50-2) → difluorosilane (13824-36-7) + trifluorosilane (13465-71-9) + monosilane (7440-21-3)

Guidance literature:

In neat (no solvent); addn. 1 equiv. of tinhydride; excess of tinhydride no further reactn.; not isolated; identified 90% SiF2H2, 5% SiF3H and 5% SiH4 in product mixt.);
