Technology Process of Tetraborane(10).

There total 16 articles about Tetraborane(10). 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: 90.0%

tetraethylammonium octahydrotriborate(1-) + tetraethylammonium borohydride → tetraborane (18283-93-7) + tetraethylammonium iodide (68-05-3)

Guidance literature:

With methyl iodide; In 1,2-dichloro-ethane; byproducts: methane; inert atmosphere, room temp., 1 h; filtn., fractional condensation (50-100 Torr, -78°C-trap);

Reference yield: 65.0%

(CH3)4N(1+)*B3H8(1-)=(CH3)4NB3H8 + boron trifluoride (7637-07-2) → tetraborane (18283-93-7) + diborane (19287-45-7)

Guidance literature:

In neat (no solvent); byproducts: (CH3)4NHBF3; BF3 condensing under N2 at -196°C onto ammonium salt, warming to0°C, stirring for 3 h, cooling to -196°C, warming slowly to room temp. while the volatiles pumping off, borane collecting at -140°C; identified by IR spectrum;
