  A practical, efficient and general method was developed for the deprotection of a variety of aromatic and aliphatic acetals to their corresponding catechol or diol derivatives using thiol functionalized on silica gel. This is an application for the well‐known commercial solid‐supported thiol (Silia MetS ® Thiol). The procedure is mild and amenable to scale‐up. It does not require inert atmosphere and

  开发了一种实用，有效且通用的方法，使用在硅胶上官能化的硫醇将各种芳族和脂族缩醛脱保护为相应的邻苯二酚或二醇衍生物。这是著名的商业固载硫醇（Silia MetS®Thiol）的应用。该过程是温和的，并且可以扩大规模。它不需要惰性气氛，并且观察到干净的转化。此方法适用于具有不同功能的取代1,3-苯并二恶唑和脂族缩醛。它提供了高收率的常规路线的优势，可以在环境温度下进行。

  日期：2008.1

  Regioselective nuclear bromination of aromatic compounds is investigated with N-bromosuccinimide as the brominating agent under UV irradiation to afford the corresponding brominated compounds. The reaction proceeds at ambient temperature (30 ± 2 °C) without any catalyst. In most of the reactions, regioselectively mono-brominated products are obtained in good to high yields. The conversion and selectivity
