Technology Process of trifluoro(iodo)silane

There total 2 articles about trifluoro(iodo)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: 1.0%

hydrogen iodide (10034-85-2) + trifluorosilane (13465-71-9) → trifluoro-iodo-silane (16865-60-4) + F3SiSH (95665-02-4) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In neat (no solvent); in a sealed glass ampoule, 298 K, conversion was 48 %, 64 and 90% after 11, 38 or 133 h, resp., under dry N2; fractionation could not be performed succesfully;

Reference yield:

difluorosilylene (13966-66-0) + iodine (7553-56-2,12190-71-5,8031-47-8) + silicon tetrafluoride (7783-61-1) → trifluoro-iodo-silane (16865-60-4) + SiF2I2 (27669-15-4) + SiFI3 (23338-93-4) + silicon tetraiodide (13465-84-4)

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;; evapd.,; the volatile products were sepd. and detected by NMR and MS;;

DOI:10.1039/DT9870001123

Reference yield: 54.0%

trifluoro-iodo-silane (16865-60-4) + HgS, red → hexafluorodisilthiane (41066-09-5) + octafluorotrisildithiane + hexafluorodisiloxane (14515-39-0) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In neat (no solvent); byproducts: HgI2; CF3SiI:HgS molar ratio was 1:2, in a sealed tube, 300 K for 7 days, under dry N2; low temp. fractionated distn., less volatile fraction was purified by passing it through a 198 K trap into a trap held at 173 K, the (F3SiS)2SiF2 was identified by NMR, its purity was 98 %;;
