allylic

This paper laid em-phasis on the study of the allylic oxidation and halogenation.

着重研究其中的烯化和卤代反应，提出合适的反应机理。

The review summarizes the methods of synthesis of keto-ionone by allylic oxidation of α-and β-ionones,which can be divided into five categories with different oxidation.

综述了α-和β-紫罗兰酮经烯化制备代紫罗兰酮的研究进展,依据不同的化剂分为五大类,详细地分析了各种方法的特点,指出了今后的发展趋势。
