Technology Process of tris(diphenylphosphinooxy)borane-triborane

There total 5 articles about tris(diphenylphosphinooxy)borane-triborane 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: 28.0%

tetraethyldiborane(6) (12081-54-8) + {(diphenylphosphinoyloxy)diethylborane}2 (92784-88-8) → {(C6H5)2PO}3B*3BH3 (108343-02-8) + bis(diphenylphosphinooxy)ethylborane (108343-01-7) + (diphenylphosphinooxy)diethylborane-borane (108343-00-6) + triethylboroxine (3043-60-5) + diphenylphosphine-borane complex

Guidance literature:

heating of the diborane and the phosphinoylborane to 120°C, stirring for 2 h, cooling to 20°C, all steps under exclusion of air and moisture; monitored by NMR;

Reference yield:

Diphenylphosphine oxide (4559-70-0) → tris(diphenylphosphinooxy)borane-triborane (108343-02-8) + bis(diphenylphosphinooxy)ethylborane (108343-01-7)

Guidance literature:

Multi-step reaction with 2 steps

2: chloroform

In chloroform;

Reference yield:

tetraethyldiborane(6) (12081-54-8) + (diphenylphosphinooxy)diethylborane (108342-97-8) → (C6H5)2POH(BH3) (108452-14-8) + tris(diphenylphosphinooxy)borane-triborane (108343-02-8) + bis(diphenylphosphinooxy)ethylborane (108343-01-7) + diphenylphosphane oxide-tris{(P-B)boran-(diphenylphosphinooxy)}borane (108452-13-7) + Diphenylphosphine oxide (4559-70-0)

Guidance literature:

byproducts: PH(C6H5)2; reaction in presence of 2-ethyl-1-hexanol under exclusion of air and moisture; dissolving of the residue in CHCl3, addn. of pentane gives Ph2P(H)OB(OP(BH3)Ph2)3, elem. anal.;

upstream raw materials:
