As 1,2-isomer has quite different chemical shifts from that of the corresponding 1,4-isomer, the ratio of these isomers in the products of NaBH4 reduction can be easily estimated from the integral data of the nmr spectrum of the products.The results are given in Table 3.
由于1,2-异构体同相应的1,4-异构体有着相当不同的化学转变，在NaBH4还原产物的这些异构体的比例可以很容易地从核磁共振光谱的生成物中估算出来.数据结果列于表3 |
