Technology Process of 1,2-dimethylborane

There total 6 articles about 1,2-dimethylborane 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: 63.0%

tetraborane (18283-93-7) + trimethyl indium (3385-78-2) → dimethyldiborane (20436-23-1,17156-88-6,6808-37-3) + dimethylindium octahydrotriborate

Guidance literature:

In neat (no solvent); room temp., 12 h; colourless viscous liquid, fractionation in vacuo at -15°C gives a white solid; elem. anal.;

DOI:10.1039/cc9960002055

Reference yield:

methyl diborane (23777-55-1) → dimethyldiborane (20436-23-1,17156-88-6,6808-37-3) + diborane (19287-45-7)

Guidance literature:

equil. react.;;

Reference yield:

bis(cyclopentadienyl)dimethylzirconium(IV) (12636-72-5) + borane tetrahydrofuran → 1.1-dimethyl borane(6) (16924-32-6) + dimethyldiborane (20436-23-1,17156-88-6,6808-37-3) + (cyclopentadienyl)2Zr((μ-H)2-tetrahydroborate)2

Guidance literature:

In tetrahydrofuran; under N2, to THF added Cp2ZrMe2, to this soln. added (at -78°C) 0.64 M BH3*THF soln. / overall B:Zr > 2:1; not isolated; NMR anal.;
