In the trial scale-up of the sulfonation of phenylchloroformate and subsequent formation of sulfonated phenyl carbonates, samples from the batch process showed a number of unexpected by-products. Because they were suspected to have an unusual ring substitution pattern, phenylchloroformate sulfonation was studied by 1H and two-dimensional nuclear magnetic resonance (NMR) techniques.

在苯氯甲酸酯磺化和随后形成磺化碳酸苯酯的试验放大中,分批过程的样品显示出许多意想不到的副产物。由于怀疑它们具有不寻常的环取代模式,因此通过 1 H 和二维核磁共振 (NMR) 技术研究了苯氯甲酸酯磺化。距离几何用于计算核间距离,用于证实核奥弗豪泽效应的观察。提出了导致这些副产物的反应机理。
