IR和NMR图谱法问世之前,土伦试剂是鉴别一般醛酮的主要方法之一,至今在教学中仍有广泛应用。但醛基被土伦试剂氧化为羧基的机理并不明确,卢西(Reusch)提出的水合中间产物论,在这里并不适用。但实验表明,氧化反应的速度快慢和羰基活性的大小是一致的。 Before the advent of IR and NMR spectroscopy, Toulon Reagent is one of the main methods to identify common aldehydes and ketones, and so far there is still a wide range of applications in teaching. However, the mechanism by which aldehyde groups are oxidized by TURON to carboxyl groups is not clear. The hydrated intermediate product theory proposed by Reusch does not apply here. However, experiments show that the speed of oxidation and carbonyl activity is the same size.
