Technology Process of Diboron tetrafluoride

There total 11 articles about Diboron tetrafluoride 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: 89.0%

tribromofluoromethane (353-54-8) + diboron tetrachloride (13701-67-2) → boron trifluoride (7637-07-2) + diboron tetrafluoride (13965-73-6)

Guidance literature:

In neat (no solvent); byproducts: CBr3Cl; heating of B2F4 and CFBr3 in a sealed tube at 130°C for 2,5 h; fractionation at -160 and -95°C yielded B2F4;

Reference yield: 81.0%

trichlorofluoromethane (75-69-4) + diboron tetrachloride (13701-67-2) → nonachlorononaborane(9) (12008-47-8) + B10Cl10 (61674-49-5) + B8Cl8 (32915-80-3) + diboron tetrafluoride (13965-73-6)

Guidance literature:

In trichlorofluoromethane; byproducts: CCl4; B2Cl4 and 10-fold excess CCl3F were heated in a sealed tube at 90°C for 61 h; partially septd. by fractionation at -95 to -160°C; products detected by (19)F- and (11)B-NMR, CCl4 by (13)C-NMR;

Reference yield: 78.0%

diboron tetrabromide (14355-29-4) + tribromofluoromethane (353-54-8) → boron trifluoride (7637-07-2) + diboron tetrafluoride (13965-73-6)

Guidance literature:

byproducts: CBr4; B2Br4 and CFBr3 were reacted in a NMR-tube at ambient temp. for 9,75 h; products detected by (19)F- and (11)B-NMR, CBr4 by (13)C-NMR;

upstream raw materials:
