Technology Process of Borane

There total 49 articles about Borane 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%

lithium borohydride + zinc(II) chloride (7646-85-7,24359-56-6) → zinc + borane (13283-31-3) + decaborane

Guidance literature:

In 1,3,5-trimethyl-benzene; for 24h; Reflux; Inert atmosphere;

DOI:10.1039/c3dt00092c

Reference yield: 82.0%

lithium borohydride + dichloro(pentamethylcyclopentadienyl)rhodium (III) dimer → ((η(5))-C5Me5Rh)2B2H2 + borane (13283-31-3)

Guidance literature:

In tetrahydrofuran; byproducts: Cl(1-), H2; Ar-atmosphere; addn. of LiBH4 to suspn. of Rh-complex (-40°C), wirming to room temp., stirring (room temp., 1 h); solvent removal (vac.), extn. into hexane, solvent removal;
