Reaction Conditions:
with sodium tetrahydroborate in acetonitrile at 20; for 0.25 h;Inert atmosphere;
Steps:
2.2-2 Synthesis of example 2
After replacing the interior of a 7 mL test tube equipped with a stirring bar with nitrogen gas,Under nitrogen flow,In this test tube,0.5 mL of acetonitrile as a reaction solvent,As a reducing agent, sodium borohydride (NaBH 4, ReagentPlus (registered trademark), manufactured by Sigma-Aldrich Japan Co.,Purity 99%) 37.8 mg (1.0 mmol)To prepare a suspension.To this suspension,147.4 mg (0.5 mmol) of triphenylchlorosilane (Ph 3 SiCl) was added,The reaction was allowed to proceed for 15 minutes while stirring at room temperature.After the reaction,Acetonitrile was distilled off,To the obtained product (mixture), 5 mL of n-hexane was added under the atmosphere, and the mixture was filtered using a silica pad,By drying,85.0 mg (0.326 mmol) of triphenylsilane (Ph 3 SiH) was isolated.The yield of triphenylsilane was 65%
