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.
