Rubidium and Cesium in Organic Synthesis

Use of rubidium in organic reactions is less common than that of cesium. Cesium compounds are important reagents in fluorine chemistry and are also used as unique bases in organic reactions.

Cesium and rubidium have important and unique positions in organic synthesis. To understand their role, their properties as metal ions should be kept in mind. They are large, highly electron-positive ions. The salts release the counter anion easily and always tend to form the naked anion . This is important aspect of their use as catalysts. These metal compounds will not take the leading part very often but always appear in supporting roles in organic reactions.
