Naphthalenes with an Me group in the 1-position gave aldehydes in good to excellent yields when oxidized with cerium(IV) ammonium nitrate (CAN) in 50% HOAc at 85°. Under the same conditions methylnaphthalenes with no Me group in a peri position gave aldehydes in fair yields but also significant amounts of 1,4-naphthoquinone.
当在50%HOAc中于85°C下用硝酸铈(IV)铵铵(CAN)氧化时,在1位上具有Me基的萘产生的醛收率非常好。在相同条件下,在周边位置没有Me基的甲基萘以适当的收率得到醛,但是也产生了大量的1,4-萘醌。
