Abstract

β-cyclodextrin based Batch, Flow-Through and “Teabag” Prototype Molecular Reactors have been assembled and used in variety of conventional synthetically useful free radical transformations (Hydrogen Transfer Reactions, Radical Cascade Reactions and Mn(OAc)3 mediated cascade/oxidation reactions. Reactions proceeded smoothly in all cases in good to excellent yields at ambient temperature in aqueous and organic media. The advantages of newly assembled setup are ease of setup, recyclability of the β-cyclodextrin media, flexibility and scope of the transformations to be performed and ease of scale-up of methodology.
