Technology Process of difluorosilane

There total 11 articles about difluorosilane 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:

fluorine (7782-41-4) + silicon (7440-21-3) → difluorosilylene (13966-66-0) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In neat (no solvent, gas phase); F2 is adsorbed to Si at 120 K up to the desired coverages, and the surface is heated at a constant rate of 4 K/s. Product is desorbed at 400-800 K, depending on coverage.; Kinetics;

Reference yield:

silane-d4 (13537-07-0) + fluorine (7782-41-4) → difluorosilylene (13966-66-0) + trifluorosilyl radical (14835-14-4) + silicon tetrafluoride (7783-61-1)

Guidance literature:

In solid matrix; byproducts: SiHD3; Irradiation (UV/VIS); dilg. SiD4 with Ar (various ratios); codeposition with F2 dild. with Ar (various ratios) on a substrate at 13.+-1. K; UV-photolysis (220-1000 nm) for 1 h; annealing to 25.+-.2 K;; not isolated, identified by IR-spectroscopy; further products;;

DOI:10.1021/j100192a020

Guidance literature:

In solid matrix; byproducts: HF, H2O, O2F; Irradiation (UV/VIS); dilg. SiH4 with Ar (various ratios); codeposition with F2 dild. with Ar (various ratios) on a substrate at 13.+-1.
