Reaction Conditions:

with sodium tetrahydroborate;iodine in acetonitrile at 100; for 24 h;Sealed tube;

Steps:

1 Example 1
In a dry 25mL reaction tube, benzyl alcohol (0.5mmol), NaBH4 (1.0mmol), I2 (0.5mmol), anhydrous acetonitrile (2mL) were sequentially added, and the tube was sealed and reacted at 100 ° C for 24 hours.Cool to room temperature, add 10 mL of water to quench the reaction, and extract three times with ethyl acetate.The organic phases were combined, dried over anhydrous magnesium sulfate, and the crude product was separated and purified by column chromatography. The target product was obtained, yield: 96%.
