Yield:3466-32-8 100%

Reaction Conditions:

with sodium periodate;ruthenium-carbon composite in water at 20; for 2 h;

Steps:

6
Add 0.01 g of Ru / C catalyst and 235 mg (1.1 mmol) of sodium periodate to the reaction flask, add 3 mL of water, and then add 203 mg (1 mmol) of 4-bromoanisole I-6 to the reaction with stirring In the flask, react for 2h at room temperature. The reaction of 4-bromoanisole was detected by TLC, and the reaction was stopped. The reaction solution was filtered and washed with dichloromethane (10 mL × 2), and the filtrate and the washing solution were combined. It was washed twice with saturated sodium chloride solution, and water was removed with anhydrous sodium sulfate. The solvent was distilled off and dried to obtain high-quality compound II-6, yield 100%.
