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:
- Guidance literature:

With
N(C2H5)3;
In
diethyl ether;
byproducts: {N(C2H5)3H}Cl; to a cooled (-78 °C) soln. of (C6H5)B(OH)2 and excess triethylamine in Et2O was added dropwise a soln. of 1,7-dichlorooctamethyldisiloxane in the same solvent, warmed to room temp., mixture was allowed to stir overnight;; filtration; evapn. of solvent; vacuum distillation afforded a colorless liquid; elem. anal.;;

melt;
byproducts: {PhBO}3, {Me2SiO}3, {Me2SiO}4; heating at 225 °C in an evacuated sealed Pyrex tube for 4 h; further byproducts obtained;; residue dissolved in dry Et2O, the resulting soln. was filtered to remove (PhBO)3, the solvent was then removed carefully under low vacuum (100mmHg); residue dissolved in C6D6 and analyzed by (29)Si NMR spectroscopy;product mixture; not isolated;;
