Technology Process of 2,2'-(B₅H₈)2

There total 1 articles about 2,2'-(B₅H₈)2 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: 17.0%

pentaborane(9) (19624-22-7) + sodium hydride (7646-69-7) → nido-decaborane (17702-41-9) + 2,2'-(B5H8)2 (28775-81-7)

Guidance literature:

With iron(III) chloride; iron(II) chloride; In tetrahydrofuran; B5H9 was condensed in vac. onto NaH at -196°C in THF, mixt. was warmed to -78°C, NaB5H8 in THF was filtered in vac. onto FeCl2, cooled to -196°C, then warmed to -78°C, stirred 1-2 h, FeCl3 was added, mixt. was stirred for 4 h; solvent was removed under vac., mixt. was allowed to warm to room temp., residue was extd. with hexane under N2, solvent was removed by evapn. under vac., evacuated at -78°C, compounds were obtained by vac. sublimation/distillation;
