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:
- Guidance literature:
-
In
benzene;
byproducts: water; refluxing (equimolar mixture, 4 h, continuous removal of water); cooling, filtration, distn. (reduced pressure), recrystn. (Et2O:petroleum ether 1:3); elem. anal.;

With
N(C2H5)3;
In
diethyl ether;
byproducts: {N(C2H5)3H}Cl, {(C6H5)BO}3, {Ph2SiO}3; to a Et2O soln. containing (C6H5)B(OH)2 and excess triethylamine at -78 °C was added dropwise a cold (-78. degree.) soln. of 1,3-dichlorotetraphenyldisiloxane in same solvent, warmed to room temp., mixt. was allowed to stir overnight, filtration; to remove (NEt3H)Cl, followed by several fractional crystn. from a mixt. of Et2O/hexane (1:1) at -15 °C to remove first (PhBO)3, (PhBO)(Ph2SiO)2 and then (Ph2SiO)3, finally (PhBO)(Ph2SiO)3 was obtained as clear colorless clusters; elem. anal.;;
- Guidance literature:
-
In
benzene;
byproducts: H2O; molar ratio of PhB(OH)2:Ph2Si(OH)2=1:2, reflux; water was removed as azeotrope, removal of excess C6H6, elem. anal.;
