摘要
本文介绍了国内外改进Reimer—Tiemann反应以及催化合成羟基苯甲醛的新方法,并进行了较详细的评述。合成羟基苯甲醛的研究进展,涉及到有机合成化学的边缘学科领域,因此,深入了解并研究这方面的课题,有重要的意义。
This paper has reviewed the newly synthetic methods of hydroxybenzald-ehyde both theoretically and practically. A [number of active reagents or/and catalysts have been incorporated in the system of Phenol-CHCl3 - NaOH for the preparation of hydroxybenzaldehyde. The approaches to this classical reaction can obviously increase the yield and selectivity of products. It is an attractive work that the special catalysts with various solvents improve the reaction. It has showed that these researches are both practical interests and theoretical significance.
