-

Yield:776-76-1 91% ,1172-76-5 5%

Reaction Conditions:

Stage #1:chloromethyldiphenylsilane in tetrahydrofuran at 30; for 10 h;
Stage #2: with hydrogenchloride in 1,4-dioxane

Steps:

1 Experiment number 1
To 0.5 ml of THF, 0.5 mmol of methyldiphenylsilyl chloride, which is a silyl halide compound, and 2.0 molar equivalents of SD were added and reacted at 30 ° C. for 10 hours to synthesize methyldiphenylsilylsodium that was a silyl sodium compound. At this time, the reaction was carried out without adding additives other than the above.The yield of sodium methyldiphenylsilyl was determined by reacting the obtained sodium methyldiphenylsilyl with hydrogen chloride in a 1,4-dioxane solution in which hydrogen chloride was dissolved to synthesize methyldiphenylsilane. It was calculated indirectly by calculating the ratio by NMR. The yield of sodium methyldiphenylsilyl is the ratio (%) of sodium methyldiphenylsilyl actually obtained to sodium methyldiphenylsilyl theoretically produced from methyldiphenylsilyl chloride added to the reaction system.FIG. 1 summarizes the reaction scheme, reaction conditions, and yield. As a result, it was revealed that methyldiphenylsilylsodium could be synthesized in a high yield of 91%.
