Technology Process of tris(trifluoromethyl)borane carbonyl

There total 1 articles about tris(trifluoromethyl)borane carbonyl 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: 88.0%

potassium tetrakis(trifluoromethyl)borate → HSO3F + boron trifluoride (7637-07-2) + tris(trifluoromethyl)borane carbonyl (438192-67-7)

Guidance literature:

With H₂SO₄; In sulfuric acid; a soln. of KB(CF3)4 in ether was placed into the flask, ether was removed, concd. H2SO4 was added in 3 portions at room temp., the mixt. was stirred vigorously until no gas evolution was observed, stirred for 7 h at 45°C; collected at -100°C, BF3 was solidified at -196°C, distilled at -85°C;
