Technology Process of dimeric (dimethylamino)difluoroborane

There total 8 articles about dimeric (dimethylamino)difluoroborane 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: 90.0%

Bis(dimethylamino)-methyl-boran (6914-63-2) + boron trifluoride (7637-07-2) → dimeric (dimethylamino)difluoroborane (58904-71-5) + (methyl)difluoroborane (373-64-8)

Guidance literature:

In xylene; when BF3 escapes BF3-stream is shut off; CH3BF2 trapped at -78°C, ((CH3)2NBF2)2 retained by high-efficiency condenser;

Reference yield: 86.0%

boron trifluoride (7637-07-2) + (dimethylamino)diphenylborane (2237-45-8) → dimeric (dimethylamino)difluoroborane (58904-71-5) + diphenylboron fluoride (36140-35-9)

Guidance literature:

In pentane; pure (C6H5)2BF obtained after ((CH3)2NBF2)2 filtered off and n-pentane evaporated;

DOI:10.1016/0022-328X(68)80063-4

Reference yield:

CF3SB{N(SCF3)2}2 → dimeric (dimethylamino)difluoroborane (58904-71-5) + 1,1,3,3-tetramethyl-2-thiourea (2782-91-4) + N,N-dimethylthiocarbamoyl fluoride (683-82-9) + trifluoromethyl dimethylcarbamodithioate

Guidance literature:

40-60°C;

upstream raw materials:
