Technology Process of sodium bis(catecholato)borate

There total 4 articles about sodium bis(catecholato)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: 97.0%

sodium tetrahydroborate (16940-66-2) + tris(catecholato)diboron (37737-62-5) → sodium bis(catecholato)borate (22364-91-6) + diborane (19287-45-7) + benzo[1,3,2]dioxaborole (274-07-7)

Guidance literature:

In diethylene glycol dimethyl ether; (N2); soln. of Na(BH4) (34.1 mmol) in diglyme was added to the phenylene compd. (68.3 mmol) in diglyme; B2H6 carried away by an N2 stream, was absorbed in acetone; stirring overnight; (N2); distn. (80-100 °C, 100 mmHg) gave a soln. of the catecholatoborane (yield 97%); the non-volatile residue dried (100 °C, 0.01 mmHg) and identfied as Na(B(O2C6H4)2) (11B NMR spectrum);

Reference yield: 86.0%

sodium tetrahydroborate (16940-66-2) + benzo[1,3,2]dioxaborole (274-07-7) → sodium bis(catecholato)borate (22364-91-6) + diborane (19287-45-7)

Guidance literature:

In diethylene glycol dimethyl ether; to a soln. of NaBH4 (22.2 mmol) in diglyme was added dropwise with stirring under N2 a soln. of catecholatoborane (44.4 mmol) in diglyme; B2H6 was absorbed in acetone (for 16 h);; after evapn. of the solvent the solid residue was dried at 100°C(1E-2 mm Hg);;

Reference yield: 59.0%

sodium tetrahydroborate (16940-66-2) + tris(catecholato)diboron (37737-62-5) → sodium bis(catecholato)borate (22364-91-6) + diborane (19287-45-7)

Guidance literature:

In diethylene glycol dimethyl ether; (N2); suspn. of NaBH4 (76.6 mmol) added to a stirred soln. of the o-phenyle compd. (51 mmol); B2H6 condensed at -196 °C (trap); after 1 h, mixt. heated to 90 °C for 90 min; (N2); pure B2H6 (condensed at -196 °C) obtained;
