摘要: Fehling试剂用于鉴定脂肪醛类化合物和还原糖类化合物,也用于还原糖类化合物的定量测定。目前国内外有机化学教材中均未提及Fehling试剂中Cu2+与酒石酸盐螯合物的结构。本文介绍了国内外对于Fehling试剂中Cu2+螯合物结构研究的最新成果,旨在对教材中Fehling试剂及其反应的知识进行补充,弥补教材知识点的局限性。

Abstract: Fehling reagent serves as an important tool for identifying aliphatic aldehydes and reducing sugars, as well as for the quantitative analysis of reducing sugars. Current organic chemistry textbooks, both domestic and international, lack discussion regarding the structure of Cu2+-tartrate chelates in Fehling reagent. This study presents recent advancements in elucidating the structure of Cu2+-tartrate chelate complexes within Fehling reagent, thereby addressing the existing knowledge gap in textbook descriptions of Fehling reagent and its associated reactions.

Key words: Fehling reagent, Potassium sodium tartrate, Chelate, Aliphatic aldehyde, Reducing carbohydrate
