91%; 5% 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%.

Reaction was carried out for varying times under the same conditions as in Example 1 except that the amount of iron complex catalyst was changed to 0.5 mmol only when the hydrosilane reactant was triphenylsilane. The results are shown in Table 2 together with the result of Example 1. It is evident from Table 2 that corresponding disilanes were produced in high yields of 50% to 100%.

86% With silver tetrafluoroborate; In dichloromethane; at 25℃; for 24h; AgBF4 (0.00125 mmol, 0.0003 g) was added to the reaction flask, dichloromethane (DCM, 2.5 ml) was added, and then 2.5 mmol of compound 1b (0.4952 g) was slowly added dropwise to the reaction flask and stirred at 25 C. After reacting for 24 hours, the product 2b (0.4426 g) was distilled under reduced pressure after the reaction was completed, and the yield was 86%.

52% With tetrabutyl ammonium fluoride; water; In dimethyl sulfoxide; at 80℃; under 760.051 Torr; for 24h;Schlenk technique; General procedure: To a glass reactor equipped with a CO2 balloon was added tetrabutylammonium fluoride trihydrate (TBAF*3H2O, 5.0×10-2 mmol), tetramethyldiphenyldisilane (0.50 mmol), water (3.1 mmol), and DMSO (1 mL). The resulting reaction mixture was stirred vigorously at 80 C. The products were confirmed by the comparison of their GC-MS spectra and 1H NMR spectra with those of authentic data. The yields were determined by the internal standard technique using a CDCl3 solution of the reaction mixture. Figure S1 shows the 1H NMR spectrum of a CDCl3 solution of the reaction mixture after 24 h. Mesitylene or triisopropylbenzene was used as the internal standard.

H2O (30 mL) was added at 0 C, and the resultingbiphasic solution was extracted with Et2O (3 × 15 mL). The combinedorganic layer was washed with brine, dried (Na2SO4), andconcentrated under reduced pressure. The resulting residue waspurified by column chromatography (silica gel, hexane) andthen by GPC (CHCl3 eluent) to give a white solid; yield: 89.2 mg(0.198 mmol, 66%) (minor/major = 1:1.2 as an inseparable mixture).
