Yield: 96%

Reaction Conditions:

with 1,1,3,3-Tetramethyldisiloxane;copper(II) bis(trifluoromethanesulfonate) in dichloromethane at 20; for 1 h;

Steps:

4.5. General procedure for reductive etherification of aldehydes and ketones
General procedure: In a screw-capped vial, 3.7 mg Cu(OTf)2 (0.01 mmol, 1 mol %) and 0.1 mL TMDS (80.6 mg, 0.6 mmol, 1.2 Si-H mol/mol substrate) were introduced to a solution of aldehyde or ketone (1 mmol) in 1.5 mL CH2Cl2. After stirring for 1 h at room temperature, the reaction was quenched with 4 mL H2O. The organic layer was extracted with CH2Cl2, dried with anhydrous MgSO4, and evaporated under reduced pressure. The crude was purified by silica gel column chromatography to obtain the symmetrical ether.
