Yield: 97%

Reaction Conditions:

with lithium aluminium tetrahydride;calcium hydride;zirconium(IV) oxide in diethylene glycol dimethyl ether at 50; for 10 h;Inert atmosphere;

Steps:

1
The 100 mL three-neck round bottom flask was dried, connected to a mechanical stirrer, a spherical condenser tube, a constant pressure funnel and a gas guiding device, and then vacuum-replaced with nitrogen three times while the hot air gun was baked to remove the attached water vapor.Under a nitrogen atmosphere, 9.3 g (0.22 mol) of CaH2, 0.38 g (0.01 mol) of lithium aluminum hydride, 25 mL of diethylene glycol dimethyl ether solvent, and 25 g of ZrO 2 ceramic balls (φ = 0.90 mm) were placed in the reaction flask.25.8 g (0.2 mol) of Me2SiCl2 was added to a constant pressure funnel, and slowly added dropwise to the reaction flask under mechanical stirring.After the completion of the dropwise addition, the mixture was heated to 50 ° C and reacted for 10 hours.The main reduction product obtained was Me2SiH2, and the reaction yield was 97%.
