Technology Process of tetrabutylammonium pentafluorophenyltrifluoroborate

There total 5 articles about tetrabutylammonium pentafluorophenyltrifluoroborate 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: 95.0%

lithium pentafluorophenyltrimethoxyborate + tetrabutylammonium bifluoride (23868-34-0) → tetrabutylammonium pentafluorophenyltrifluoroborate (912292-08-1) + tetrabutylammonium bis(pentafluorophenyl)difluoroborate (912292-09-2)

Guidance literature:

With HF; In dichloromethane; hydrogen fluoride; byproducts: LiHF2, MeOH, C6F5H; aq. HF; under Ar, teflon-perfluoropropylene block copolymer vessel, aq. soln. ofBu4N-compd. was added to CH2Cl2 soln. of Li-compd., shaking; standing for 30 min to separate the phases, yields were determined by (19)F NMR;

DOI:10.1002/zaac.200500083

Reference yield: 93.0%

tetrabutylammomium bromide (1643-19-2) + potassium perfluorophenyltrifluoroborate → tetrabutylammonium pentafluorophenyltrifluoroborate (912292-08-1)

Guidance literature:

In acetonitrile; at 22 ℃; for 2h;

DOI:10.3762/bjoc.13.69

Reference yield: 22.0%

lithium pentafluorophenyltrimethoxyborate + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) + tetrabutylammomium bromide (1643-19-2) → tetrabutylammonium pentafluorophenyltrifluoroborate (912292-08-1) + tetrabutylammonium bis(pentafluorophenyl)difluoroborate (912292-09-2)

Guidance literature:

In dichloromethane; hydrogen fluoride; byproducts: C6F5H, LiBr; aq. HF; under Ar, teflon-perfluoropropylene block copolymer vessel, CH2Cl2 was added to a mixt. of solid Li-compd. and 1 equiv. of Bu4NBr, stirring for several min, 48 % aq. HF was added; yields were determined by (19)F NMR in the org. phase;
