Technology Process of Silanethiol, trifluoro-

There total 9 articles about Silanethiol, trifluoro- 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: 68.0%

hexafluorodisilthiane (41066-09-5) + hydrogen bromide (10035-10-6,12258-64-9) → hexafluorodisiloxane (14515-39-0) + F3SiSH (95665-02-4) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In neat (no solvent); byproducts: CF3SiBr; under dry N2, in a sealed tube, 60 h at room temp., molar ratio of silane and HBr was 1:1, an other non-volatile product was also formed; fractionated distn. at a low-temp. column, S-compds. were trapped at 143K, SiF4 at 77 K;

DOI:10.1002/1521-3749(200106)627:6<1217::AID-ZAAC1217>3.0.CO;2-B

Reference yield: 2.0%

trifluorosilane (13465-71-9) + sulfur (7704-34-9) → F2Si(H)SH (24628-34-0) + hexafluorodisiloxane (14515-39-0) + F3SiSH (95665-02-4) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In gas; byproducts: H2S; equimolar amts. of F3SiH and S was reacted in an ampoule at 620 K for 48h; yield of F3SiSH was increased to 6 % at 620 K during 10 h;; volatiles were trapped at 123 and 77 K, fractionated distn., products were identified by NMR and vapor phase IR;

DOI:10.1002/1521-3749(200106)627:6<1217::AID-ZAAC1217>3.0.CO;2-B

Reference yield: 1.0%

hexafluorodisilthiane (41066-09-5) + hydrogen sulfide (7783-06-4) → F3SiSH (95665-02-4) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In gas; excess of H2S, room temp., 7 h, under dry N2; detected by IR;
