Technology Process of lithium dihydrido dimethyl borate

There total 1 articles about lithium dihydrido dimethyl 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: 22.0%

methyllithium (917-54-4) + borane tetrahydrofuran → lithium borohydride + lithium trimethylhydroborate (63526-12-5) + lithium tetramethylborate(1-) (2169-38-2) + lithium dihydrido dimethyl borate (84280-31-9)

Guidance literature:

In tetrahydrofuran; diethyl ether; under dry N2, soln. of BH3 in THF cooled to -70°C, ethereal soln. of MeLi added within 20 min with vigorously stirring, warmed to -20°C; not isolated, detected by NMR;

Reference yield:

lithium trihydromethylborate (52950-75-1) + methyltris(2,6-diisopropylphenolato)titanium (1303613-03-7) + lithium dihydrido dimethyl borate (84280-31-9) → tetrakis(2,6-diisopropylphenolato)titanium

Guidance literature:

In tetrahydrofuran; diethyl ether; byproducts: B(CH3)3; N2, a soln. of B compds. (THF) added to a soln. of Ti compd. (diethyl ether), stirred for 30 min; solvent removed, residue dissolved (pentane), filtered, concd., stored at -30°C.; NMR, XRD;
