Technology Process of Trimethylphosphonium tetrafluoroborate

There total 3 articles about Trimethylphosphonium tetrafluoroborate 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:

[RuCl(=CHCH3)(CO)(P(i)Pr3)2]BF4 + trimethylphosphane (594-09-2) → tri-tert-butylphosphine tetrafluoroborate (154358-50-6) + [RuCl(CH=CH2)(CO)(P(i)Pr3)2] (104834-22-2)

Guidance literature:

In dichloromethane-d2; under Ar; a soln. of Ru-contg. compd. (0.06 mmol) in CD2Cl2 was treated with PMe3 (0.06 mmol); a quick change of colour from yellow to red; detd. by (1)H and (31)P NMR spectra;
