摘要：

Primary benzylic alcohols are selectively oxidized to the corresponding aromatic aldehydes by molecular oxygen at atmospheric pressure, under Br-2-HNO3 catalysis in a biphasic medium (1,2-dichloroethane-water, 5:1) at 60 degreesC. Under paragonable experimental conditions the aliphatic alcohols are oxidized to esters.
