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
not given;
byproducts: {N(C2H5)3H}Cl; (3+3) cyclocondensation reaction of 1,3-dichlorotetramethyldisiloxane with phenylboric acid in the presence of triethylamine as a hydrogen halide acceptor;; product mixture obtained; detected by (29)Si NMR; (C6H5BO)((CH3)2SiO)2 was purified by vacuum distillation;;
- Guidance literature:
-
With
K(OSiMe3);
In
melt;
byproducts: {PhBO}3, {Me2SiO}3, {Me2SiO}4; heating at 150 °C in in presence of 1.0 mol% K(OSiMe3 in an sealed glass tube for 1.5 h;; further by-product (Me2SiO)n; 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; not isolated;;
- Guidance literature:
