General procedure: Cobalt chloride · THF 1.5 (2.4 mg, 5 mol%) was placed in a Schlenk tube in an argon atmosphere glove box. Then dichloromethane (2 mL),Ethoxydimethylphenylsilane (40 μL, 0.2 mmol) and chloromethyl methyl ether (46 μL, 0.6 mmol) were added and stirred at room temperature (20 ° C.) for 1 hour.Thereafter, it was filtered through a glass fiber filter (ADVANTEC, GA-100) and washed with dichloromethane. The filtrate was taken out of the glove box and concentrated under high vacuum. After mesitylene (internal standard, 8 μL, 0.0575 mmol) was added, 1 H NMR (CDCl 3) was measured to show that chlorodimethylphenylsilane was produced in a 70% yield.confirmed.
