Technology Process of sodium phenyltris(pyrazolyl)borate

There total 2 articles about sodium phenyltris(pyrazolyl)borate 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: 100.0%

NH-pyrazole (288-13-1) + sodium hydride (7646-69-7) + phenylboronic acid (98-80-6) → sodium phenyltris(pyrazolyl)borate (80583-77-3)

Guidance literature:

at 200 ℃; for 0.25h; Microwave irradiation; Inert atmosphere;

DOI:10.1002/ejic.201501254

Reference yield: 20.0%

NH-pyrazole (288-13-1) + phenylboronic acid (98-80-6) → sodium phenyltris(pyrazolyl)borate (80583-77-3)

Guidance literature:

In water; acetone; diethylene glycol; to soln. of pyrazole and diglyme at 120°C was added dropwise over 30 min soln. of B-complex in aq. acetone, acetone and H2O were removeduntil the head temp. reached the boiling point of diglyme, mixt. was cooled to 50°C, treated with NaH; mixt. was heated, diglyme was removed by distillation for 45 min, cooled to room temp. under N2, treated with H2O, filtered, H2O was removed invac. at room temp., residue was triturated with ether and hexane;
