Technology Process of Diboron tetrachloride

There total 4 articles about Diboron tetrachloride 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: 50.0%

boron trichloride (10294-34-5) → diboron tetrachloride (13701-67-2) + mercury(II) chloride (51312-24-4)

Guidance literature:

circulation of B2Cl4 beetwen Hg electrodes, glimm discharge; 1-2 Torr; condensation of B2Cl4 at -78.5°C in discharge tube; no HgCl condensed in the discharge tube;

DOI:10.1021/ja01177a538

Reference yield: 17.0%

hydrogen (1333-74-0) + boron trichloride (10294-34-5) → monochlorodiborane (17927-57-0) + dichloroborane (10325-39-0) + diboron tetrachloride (13701-67-2) + diborane (19287-45-7)

Guidance literature:

flowing equimolar amts. of BCl3 and H2 through quartz pipe heated to 900°C; residence time 1.7 s;

DOI:10.1021/ic50007a067

Reference yield:

tris(trimethylsilyl)phosphane-tetrachlorodiborane(4) (142981-23-5) → boron trichloride (10294-34-5) + diboron tetrachloride (13701-67-2)

Guidance literature:
