Supported reagents are very important because of their high efficiency and very mild reaction conditions. 1 The use of heterogeneous reactions on solid support is interesting because such reactions can be more selective and milder than ordinary homogeneous reactions. Silica-gel and alumina are among the most important and useful supports for a variety of transformations of functional groups. Some reactions can occur even without solvent. 2 Silica-gel shows ...
